Familiar with these picture?

The logo is free advertising if the images get shared or published. Most manufacturers of consumer grade cameras incorporate a Logo in the image. Some let you disable the Logo overlay, but most do not.

As a good friend of mine who designs cameras said to me...... “why have junk on the screen, like logo’s when a customer has paid a lot for those pixels !” Every one of those expensive pixels should be made available to the customer, if desired !

most noteable it offers 25hz. in the QVGA dongle space you can only get a modified ThermApp to do that. If HTI and IRAY are just rebrands of one another, it gets interesting in terms of competition. The sensor they built looks very capable and form the teardown, the lens looks like a good piece of germanium.

'Interesting'  :bullshit: comparison with a Boson 640.

Shows what a bit of unsharp mask can do to a 384 image while a bit of blur on the Boson 640. 

Ambassador, what do the images from your actual camera look like ?

You must not deep climb into. You can open case and disconnect shutter. So i can see shutter is connected with normal 2pin connector (data connector must not be disconnected). That's all. Then you can make a couple fotos. There is only one single PCB. But if you don't want, I can understand you.  :-BROKE

Hi guys. Long time lurker, first time poster  :D

I just received my HT-301, and coming from a lepton 3.5 ("DIY-Thermocam") I am frankly gobsmacked at how much better the HT-301 is! US$770 isn't exactly chump change, especially with an exchange rate that sure ain't what it was about 5 years ago... So it was a bit of a gamble in a way, but one that appears to have paid off.

My first suspicions were that the sample photos on HTI's website were a little too good to be true, but I can safely say they have not been doctored. They are, however, probably good examples of excessive noise correction that seems to be applied by default with the HTI app. There is every possiblity that I don't know what I'm talking about yet.

Leads me to my next point, the HTI app is at best functional... But in my case, far from it. I use a Google pixel 3a XL which runs Android 10, and to be fair "Mr Lin" (the chap who answers HTI's email enquiries, and I think runs the YouTube channel) did say to me that it won't support my phone, but that it will support the Mrs' Huawei mate 20 Pro running a bastardised version of Android 9. Mr Lin was very quick with email replies, tho many of them featured only one word ???

So the app works on the Huawei, not much to write home about and a lovely watermark for my trouble, covering probably 50 US dollars worth of pixels :palm:

FFC clicks the shutter away and seems to change the image for the better, but the image does have noticeably uneven "illumination" with a brighter ring around the periphery (like vignetting, but the opposite) along with a funny looking defect in the centre of the frame, kind of reminds me of spherical aberration. I have since noticed a very similar "feature" in photos taken with other 384x288 17μm modules that appear to be the same thing with different branding.

Which leads to the next point...  The ht-301 works like a charm with ThermViewer, even on Android 10 :clap: and without going into it too much, it's a heck of an improvement over the HTI app, even when on a phone it works with ::) lens cap on and hold down the eraser (nuc?) looking button and... bam! The defects in the previous paragraph are gone.

And the final point I'll make, the lens sure is a loose fit in it's focusing threads! I suspect that may be intentional, to protect the sales of thermal rifle sights that need to hold a zero, not that HTI appear to sell one ;D However it doesn't appear that it will fall out, with (not very) hard stops slightly past Infinity and at around 120mm from the lens, definitely less than the 190mm on the spec sheet.




Attached is a photo that is definitely something a lepton could not resolve, it would appear to be the brightly illuminated blood vessels on the back of the Mrs hand. Focus isn't nailed, and it's tricky to get stills to come out as good as they appear live... Tricky to hit the shutter button without shaking the camera I suspect.


Cheers

Thanks for the review.

The illumination ring is due to the shutter being between the lens and the sensor.
Doing a nuc with the shutter corrects the sensor non uniformity but leaves that of the lens untouched.

That's why a nuc done in front of the lens is better: you take into account everything.

Подкажите плз. нахожусь в раздумьях насчет покупки тепловизора, в данный момент рассматриваю следующие:

- Seek Compact pro-type C
- Hti HT-301
- KCH-T3S

Почитав за каждый тепловизор, понял, что у двух последних есть фирменный логотип на картинке, связавшись с Support каждого понял, что они убирать не собираются лого , но по спец.заказу  Hti согласились это сделать но за "дорого".
Собственно у меня цели применения тепловизора самые обширные, вплоть до проверки теплоутечек в домах. Понимаю, что ни один из данных тепловизоров не проходил РСТ и тем самым будет проблематично его "поверка".
Склоняюсь к модельке от Seek т.к. там нет на экране лого да и бренд американский хороший, но понима, что с размерами матрицы проигрываю (((
KCH-T3PRO не рассматриваю в связи с его дороговизной и по сути функционал как KCH-T3S

Hi, I used Google to translate but sounds like you like the HTI 301 but don't want the watermark that the HTI app forces upon you.

The fix for that is easy, use "ThermViewer" instead of the HTI app. It's better in every way, much clearer images, "super res", and lens cap correction (NUC right?) really clears up the "aberrations" you see in the HTI app. But best of all, there is no annoying watermark wasting your precious pixels 8)

Downside is that it cost 35 US dollars, but hey your wallet is gonna take a hit buying the camera, so you may as well enjoy it.

Yes, that's the one that I use.

Although it does not say anything about HTI 301 compatibility, it worked straight away for me. Because I have a pixel phone running Android 10, the HTI app does not work so this was my only option, but also the best option 8)

I spoke to the developer, Jinhua, by email (nice guy!) and he suggested that the HTI is most likely made by the same OEM as the Xtherm. The app identifies the camera as a T3 when plugged into the phone.


Cheers

Edit: free to download, and you get 3 day trial period, after that it is limited to 5 minutes before the app closes (open it again and your get another 5 minutes). The licence is associated with the cameras serial number, so you can install it on multiple phones no problem.

if you have Taobao account you can easily get this.

If you buy from taobao, you need a taobao agent. Agents usually take 5% of price and don't forget shipping cost (and may be custom fee).
On aliexpress it costs 670$ with free shipping (but may be you need pay later custom fee):

Hi all,
I also received my camera HT-301. Pretty piece of equipment, just the software is a little basic.
What other software can run this camera for Android? Also I want to run it on my laptop(win 10). Do you think it is possible?

The last question is about the lenses. Now it is 13mm. I think that with 35mm lens it will be easy to see animals on several hundred meters. Someone did this kind of project?

Стою перед выбором покупки тепловизора, сейчас рассматриваю следующие модели (матрица 384*288):

- Thermal Expert Q1 Plus -  (9Гц , материал линзы- Германий)
- iRay XTherm T3 Pro - (25Гц , материал линзы- ? )
- HT-301 - (25Гц , материал линзы- ? )

Цена практически одинаковая у них.
Совместимо ли программное обеспечение от HT-301 с программным обеспечением от Thermal Expert Q1 Plus   ?

Понравился софт у Thermal Expert Q1 Plus - http://www.i3-thermalexpert.com/support/android-app-ios-app/?ckattempt=1
И вообще в целом софт у тепловизоров iRay и HT будет совместим между собой ?

Вот инструкция на русском Thermal Expert Q1 Plus - https://yadi.sk/d/ru-DYHhB3agXH2 (меня пугает частота кадров низкая). Описание Thermal Expert Q1 Plus - http://www.i3-thermalexpert.com/products/t-e-narrow/
Подскажите советом пожалуйста.

p.s: и наверно уже покупать из-за границы станет накладно т.к. в РФ вступаю скоро (с 01.01.2020) новые таможенные правила по уплате гос.пошлины с товаров на сумму свыше 250$, сейчас до 500$

Some more. All captured using ThermViewer with superresolution enabled, on a Galaxy S9+.

Edit: No processing beyond that.

I tried to investigate, wrote to  X-infrared(The T3S producer) but the only thing they replied was that they look quite similar, nothing more.

Xinfrared = Iray = manufacturer of IR sensor
HTI = Dongguan Xintai Instrument = manufacturer of various instruments

A partnership would be a win-win for them.

It's maybe time to create a patreon to make Dave do IR specific teardowns :D

I bought HT-301 on amazon.uk https://amzn.to/2Jcoqns a month ago and use it couple weeks.

I have not any thermal camera before, but I saw many reviews and tests of seek thermal and others thermal cameras.
I think, that hardware of ht-301 is good enough. Photos and video are  detailed and not noisy.
And 13mm lens plays here the most important role.
There are many other thermal cameras with QVGA resolution and small lens, but quality of their images are worse.
HT-301 video is smooth with 25Hz. But sometimes it is only 23-24Hz, may be it depends on phone. Video is only without sound.

23Hz

25Hz with all types of pallets
https://youtu.be/F9461Vfi_hA

Unfortunately you can not make long video with android App "Hti image". Video will be splitted into 3 minutes parts (each part 200 megabyte).
And there is a small problem with shutter. It makes automatically recalibration  every 2-3 minutes and sometimes this causes 1 second freeze moments in video.
But if you make manual recalibration before you start video, you can get 1-2 minutes without freeze moments.
I hope it will be fixed with software update.

Freeze moment

Resolution of photos and video is 1420x1080. There is no possibility  to get RAW Image (384x288). There is only 1420x1080 increased resolution with "Hti Xintai" logo. Logo sometimes blinking on video. I think, some options of temperature measurement cause it.
All pictures and video will be storaged in internal phone memory. There is no possibility to storage on SD card.
So, internal memory of your phone must have enough free space. I have now only 2Gb free space and this is a little problem for me.

Accuracy of temperature measurement is correct, but depends on setting. You need to choose right distance in setting, otherwise accuracy get worse.

Camera can measure temperature up to 600-680°C and it depends on distance setting too.
To measure high temperature you need to change the temperature range, but before that you need to choose one of temperature measurement, otherwise software will be crashed.

Minimum focus distance is about 15cm. It would be desirable a bit smaller for very small smd or electric parts, but for other things this focus distance is O.K.
I tried to screw out lens to reduce focus distance, but it seems that lens has a locking inside. I plan to buy ZnSe lens, but I don't know which diameter and focus is better.
If somebody has any idea, please write me.

There is a considerable amount of sharpening applied to every single image. You wouldn't be able to compare it side by side with the TS3. 

No Access to raw images and removal of that logo is a strong deal breaker. It looks like they did a good job on the lens, how we vignetting is seen more than once.

HT301 goes to 400C with 2C/2% accuracy, which is NOT T3S. It is actually T3Pro, which is $1150 from IRay.
So, basically HT301 is a T3Pro sold at T3S price.

Never mind. Just called an IRay distributor, and they claim HT-301 is not rebadged T3Pro. HTi also claimed it was an in-house designed model.
It could be based on the same sensor, but the rest are not the same as far as I know from the conversations.

What is accuracy? It's just how exactly you measure and calculate a temperature. Software makes a calculating. But may be you are right and T3S Pro has a better sensor.
Or T3S and T3S Pro have same sensor, but sensor of T3S has manufacture faults, like Flir  E-series.

That in conjunction with added artificial noise, i would argue you can't measure accurately when  strong noise is present.

That is exactly what Flir does. Everyone back then was puzzled when the E4 hacking thread started why would they do it . As part of the "tune up"  ::) the noise parameter was removed which resulted in better image.

For people interested in removing the HTI or Xtherm logo and do custom image processing (NUC,denoising...) . I know it's possible to directly acquire frames of raw data from Xtherm T3s through the UVC protocol. This may also work for HTI dongles.
T3s identify themselves as UVC cameras when connected to phones and desktop computers, the frames grabed from them are 292*384*2 bytes (288*384*16bits+some auxiliary data).  Some magic commands may needs to be sent to them to do initialization and shutter calibration.
This is how I get it to work with OpenCV
Code: [Select]
        self.camera.set(cv2.CAP_PROP_CONVERT_RGB, 0)  # CV_CAP_PROP_CONVERT_RGB
        # CV_CAP_PROP_ZOOM use raw mode
        self.camera.set(cv2.CAP_PROP_ZOOM, 0x8004)
        # CV_CAP_PROP_ZOOM calibrate
        self.camera.set(cv2.CAP_PROP_ZOOM, 0x8000)
There is a SDK (with poor documentation) for T3s with .dll and .so to translate the grabbed frame to temperature data, you may try to get them from the vendor. If you can't, I may help you when I have the time.

Besides, after around 4 months from purchase, 2 dead pixels appeared in the frames grabbed by my Xtherm T3s. As there is no public solution to cancel them in firmware, I have to return it for service. It's easy as I lived in the same city of the manufactuer, but it may be potentially troublesome for customers not in China. Please be aware before buying them.

Hello,
can you tell me if this defect is widespread among the users of this camera?
Eventually only two pixels burned seriously compromise the image? Is there a risk that others will burn?

Or are these drawbacks in isolated cases?

Alessio

Sorry but I didn't do a survey, the only sample is the one in my hand. :-// The deadpixels are annoying with the official app, but it looks like Thermviewer has the ability to mask them and, of course, you can write your code.
I'm pretty sure they are dead pixels since the temperature readout of the two points is precisely 20 degC.

Yes, but this requires some reverse engineering. I wouldn't like to spend my time on it without any financial incentive. However, I guess the simplest solution you can try is to replace

May be you need to find calibration data and add dead pixels in calibration file.

New user. Hi everyone. Lurker, for a while, Patreon supporter.

Now this is a cool little camera. Can confirm, ThermViewer does work with this device. I am using a OnePlus6 on android 8.1.0 (I know that's a bit old for this device, but I can also confirm it works with xprivacy LUA + xposed + root). Annoyingly, I must turn on OTG storage in advanced android settings first, then the camera works. Therm viewer seems to get the temperatures WAY wrong compared to stock XTI app - it sees my plasma screen as 400F+ but it's really 120f. First time with the app today, and hopefully I'm just missing something (It also does not to auto-cal regularly, compared to stock app, but the calibrate button does appear to work.)

First impressions: I am surprised at how narrow the FOV is - you really need to be "abnormally far" from your subject. I'd love to find a "drop-in" wide angle germanium lens that I can mount, replacing the stock one for casual use.

To counter NinetySix's comment about the loose threads -mine are nice and tight when focus is set for far/infinity. It feels like they placed a nitrile or viton o-ring on it, nice and viscous - but now it's just a bit TOO tight unless you have a phone case also gripping the USB connection to stiffen everything up. I would prefer for the machining to be more precise instead of an o-ring as a cheap fix. Sounds like a couple grains of sand are in the threads. Change your tooling inserts more frequently, they are cheap! Spend just a little bit extra time CLEANING up the threads and you don't need a o-ring. I wonder if the grit in the threads is what possibly caused dead pixels from another user in the thread. Apologies, that's for a Xtherm T3s

RBSonic's photos and videos really show off the best bits of this device. I'm still learning it. You need to get the focus correct - you forget how nice autofocus is. That being said - the lens on this is awesome. I'll borrow a quote from motor sport: "There's no replacement for displacement", and the lens diameter for this device has got to be at least twice the diameter of a comparable Flir or Seek.

The best aspect of this device, for me, is the frame rate:


Throw your FLIR and Seek in the garbage.

(ok, don't actually do that, donate it, but I'm rather amazed by this device and it was amusing to make that statement)

Pretty, but without knowing even relative temperatures it's fairly meaningless. For all we know those servers could be running at below freezing. Or about to melt.

Edit: On reflection, it's possible that this post might look like an attack of sour grapes or something, but I assure you it wasn't meant to be. The video shows the excellent frame rate but also the main issues with this camera (not being able to fix the range, etc).

After unpacking the apk with apktool or any zip utility (like 7zip).
To repack and resign the apk, you will need JDK and see https://gressie.wordpress.com/2012/06/14/how-to-properly-re-assign-a-signature-to-an-android-apk-file/ . (generate key using keytool first, like
Code: [Select]
keytool -genkey -alias nt.android -keyalg RSA -validity 20000 -keystorent.keystore)

Hi Dunkemhigh,
I recorded this with a trial version of ThermViewer. I wasn't meaning to show off temperatures with this video - I was just tooling around looking at some interesting items. But yes, I do totally agree with you, not fixing the range is annoying - using thermviewer, it often gets the temperature reading VERY wrong, but in a couple of the 40 second segments I did get it to work and it is reporting a temperature that is within 10 deg of the thermal sensors I have in the hot isle, so I included it for them. I have found that if I mount the camera, turn on OTG, then open the HTI image app, close the HTI image app, THEN open ThermViewer - the temperature ratings in therm viewer then start to work and not report hundreds of degrees incorrectly.

ThermViewer on my phone is very buggy, locking the temperature scales does not appear to work. Half of the time it opens sideways, and the trial button is off the screen - need to force quit and re-open. Again, I've not found/read a manual for the app. I have a Oneplus6. Image quality is best with ThermViewer, though options to control gradient scaling and etc are either broken or not useful enough.


So, there's a known issue with the HTI-301 where it's not possible to configure it to only measure within a set range of temperatures? This isn't a camera-app specific feature? If so, perhaps it can still be "faked" as a post-process by the app by taking the reported min-max and applying a scaling gradient? (In much the same way you can apply brightness/contrast offsets, or adjust the gamma curve)

Not having one, I can't say for sure (happy to be given one to try!), but the A1 has that 'feature' and it doesn't use a phone app. Don't know why - surely can't be hard to implement. Other makes of camera allow setting a fixed range, both those using a phone app and standalone devices.

Ciao alex871, I'll have to give that app a try when I have time to play with it. Google play allows a 2 hour refund after purchase. Grazie.

I found the instructions for the ThermViewer app - apparently long-pressing on the record button enables >40 second videos. Instruction graphic attached here. Their website is nearly empty, however: https://thermviewer.com/

How does the quality of the HTI-19 compare to that of similar cameras from FLIR or Fluke?

https://amazon.com/Resolution-Infrared-Included-Lightweight-Comfortable/dp/B07MGZP12J

I'm aware HTI isn't a brand name, but the fact that the costs are an order of magnitude lower seems almost too good to be true.

for all we know, this one looks very suspiciously close to the Seek core and lens. Quality can mean very different things but image quality wise a E4 is way ahead.

I believe TS3 series and HT301 are the same unit hardware wise, and my TS3 works fine with my Mate 30 Pro 5G.
Did you get the software done correctly? You might need to enable 3rd party apps and download apk from HTI directly.

Sorry, I was referring to thermapp plus not working with the 301. No trouble with the the HTI app downloaded directly from the HTI website (instead of from the Play store) on both my partner's mate 20 pro or my pixel 3a xl, both running Android 10. The play store version is only good for Android 9, and it does warn you of that, which is nice I guess.

I found some sample images online, and the FLIR images are indeed much clearer. You get what your pay for.

I'm gonna have to disagree with that one. Yes they have done a good job implementing msx with the visible light camera, but there sure ain't much detail when it's set to thermal only. 80x60 resolution is just not in the same league as the hti-301, and call me a purist, but I'm just not a fan of visible/thermal composite images... Especially when it's dark ;D

If it's a successfully hacked E4 with 320x240 (or whatever they can get up to) resolution then maybe, but it's not really an E4 any more then :popcorn:

A friend of mine has a flir E75, and though we haven't done a side by side comparison, he was blown away by the picture on the ht301, especially the frame rate.... Even though his does 30hz  :o doesn't have to manually focus it either, and it can likely handle being dropped too!

This calls for a side by side shootout  8) once I fix the wonky usb-c plug on my 301 that is..... Anybody else having trouble with it falling out of their phone, or the connection dropping out? My charge port is brand new, and it's definitely not dirt causing it.

Are you sure you mean the TE-Q1? The Android app allows locking of the range, and once locked the colours don't change. It's not obvious how to put the lock on or how to change the range having done so, but you can do it :)

Yes. Back in some other thread I had some other guy agreeing with me. I lock the ranges but as I move the camera around the colors change.

In ThermViewer you can configure it to save temperature data, I think it saves it as a .CSV file. Annoyingly, it creates a new folder for each image and temperature data file, which makes for a huge mess of folders in the Google photos app |O

I think Thermovision_JoeC might be able to analyse the data. The .txt file contains temperature values like "3072 2983 2975 3004" for 30.72, 29.83, 29.75, 30.04 deg C. I assume that's the value for each and every pixel

If the file coding is that simple, then a bit of file manipulation (hex editor, spreadsheet or even NotePad++)  and then Image J to display.  No software authoring needed.

Image J can import a 'text image' where it gets a text file with each pixel a text value.

Be very careful with the fpc ribbon cable for the USB plug, especially where it is folded 180 degrees then stuffed into a very tight gap between the USB plug PCB and the main board & shutter...

I can only imagine that a hard 180 degrees crease of an fpc ribbon is generally considered poor practise. The copper had snapped at the bend, only the polyimide was holding it together.

After only the 2nd disassembly... The first was due to water ingress (they could have made this camera ip67 with very little effort or added cost!) which had me worried... The camera just wasn't working at all, no click from the shutter no detection of anything by the phone, open it up and rinse it out with IPA, let it dry, reassemble and it works perfectly again... Then the USB plug seemed to be the issue, like constantly disconnecting unless you held the camera firmly against the phone, and eventually not working at all any more.

I've emailed HTI but I guess they are having a week off for lunar new year

I may have just been unlucky, but I think it's safe to say that the fpc ribbon really wasn't designed with being able to access the internals in mind.

A brief Google search found the below on another forum, from a design guide for LCD displays:

Quote
Typical FPC are rated 0.3 mm thick at the contact point stiffener. This is not the bending point.
Most FPC are thinner away from that point. For an FPC that is 0.120 mm thick in the bend area, the minimum bend radius is 1.2 mm for a 90 degree bend. A 180° bend requires a larger radius to prevent creasing. Small radius bends greater than 90° should be formed ONCE and not unbent.

There is probably less than 1mm of room for the 180 degree bend in the fpc on the 301, so if the last sentence above is anything to go by, you're gonna need to replace the ribbon should you ever need to take the USB plug out of the camera...

If you get it wet, just take the back cover off and rinse with isopropyl alcohol, save yourself some grief by not moving the fpc for the usb-c

Im ordering the ht-301, seems pretty awesome!

Now here is the big question...... Would it somehow be possible to use this somehow connected/strapped to a DJI Mavic Mini (249g)?
The small size of this is good for regulations, so if its possible somehow to use this for this kind of application, that would be awesome!

Any ideas?

Those videos are very impressive, but unless the temperature range can be locked they're much less useful than first appears. For instance, suppose you had a second pan of whatever it is and you want to just check if this one is close to the same temperature. You pan to the other, ah, pan and see that the colour is a good match. Simples. except if you can't lock the palette range then the colour is pretty meaningless as soon as you change the average temperature in the view.

Those videos are very impressive, but unless the temperature range can be locked they're much less useful than first appears. For instance, suppose you had a second pan of whatever it is and you want to just check if this one is close to the same temperature. You pan to the other, ah, pan and see that the colour is a good match. Simples. except if you can't lock the palette range then the colour is pretty meaningless as soon as you change the average temperature in the view.

It is possible to block but in the video I did not

This calls for a side by side shootout  8) once I fix the wonky usb-c plug on my 301 that is..... Anybody else having trouble with it falling out of their phone, or the connection dropping out? My charge port is brand new, and it's definitely not dirt causing it.

Yup. And I posted a solution that works for my device today. Copying from that thread:

"The HT-301 is a great thermal imaging camera, but mine is less-than-great at reliably connecting to my Samsung Galaxy S9+ over USB-C. The app will often close because of a lost connection, and I have had to use a rubber band around the camera and phone just to hold it in the right spot (once I find it) so as to avoid losing the connection. That solution kind of works most of the time.

But I found a solution that does work. All of the time.

I have a few USB-C in-line power meters that pass data through. For reasons unknown to me, the HT-301 works perfectly when connected to the phone through a power meter. Directly? It almost never works the first couple of tries and is shaky thereafter. I don't understand why this would work, but it absolutely does. If anyone out there is having the same issue, try this. You'll once again be thrilled with your purchase. And if anyone out there understands what's going on here, I'm certainly curious.

Very interested in hearing whether it works for yours as well.

(Photos in the other thread. For some reason I can't convince them to embed here.)

Does it come with a protective carrier case and what does it look like?

I posted in that thread... But what I'll say is, I've often gotten a far better connection using a short 90 degree USB-c extension lead, better at both ends. I think overall it's a fairly low quality plug that it comes with, and compared to better plugs - such as the kind that usually come with a phone, the charger lead on my last few Nexus/pixel devices has been top notch and all held up well for years... Perhaps it's just a bit more fussy about whom it mates with.

Also, does anyone know if we can buy alternative lenses for the HT 301? Are there any standards for the screw size / sensor sizes for this type of camera?

There is some information about screw size:

I'm tired of looking for information. Is it possible to block the color palette in the native HT 301 app?
If there is, how do I do it?

You need to ask people who can decompile and work with HTI Image.apk file

OnePlus 7Pro + HT-301
Temperature meter, liar.
I tried all the settings... In the photo, the best result!
The result with the settings is like in the picture.
All other devices are calibrated, their errors are known to the owner.
Make your (or repeat my) experiment and see the measurements.
When I set all the settings as in the tutorials, the results were very bad (incorrect).

Of cause you have incorrect measements. You forgot that thermal conductivity of glass is not 100%. So, temperature of glass is not equal temperature of water inside.
Just find dark color aluminium cup (coca-cola or pepsi can) and try again. And don't forget to set new setting (espesially emissivity)

I will do as you advise. But the truthful result is doubtful.
The error of the glass radiation can not be so great.

I measured boiled water and ice water. And result was O.K.

Hi Guys,

First time seeing HTI capabilities but it surely look amazing! However, I understand that the post processing is not enabled with non-radiometric images.
Plus they dont have a software dedicated for the same. Please confirm this. Thank you in advance.

You can get raw data file with thermviewer app, but only in .txt format. If someone will write converter  to convert .txt raw file to other thermal image format, we can use the post processing of other company like flir. But now we have not this converter and the post processing is not available.

Hello,

I was wondering if there was a way to get the HT-301 to work on PC?

Thank you
