To be hornest - I got from Hikmicro a M10, B20 and Pocket2 to test for the 2 books I have written about thermography. When I decided to keep the Pocket2 I got a surprisingly great deal.
Is there any difference between the B20 and Pocket 2 beside the better screen of the Pocket 2? I think Hikmicro will soon have to release new handhelds (B-series) that also have this 640x480 touchscreen.

I can only hope that the competition will get up and push new developments so that we experience the same development as in the outdoor area: There are already VOx sensors with 640x480 and <20mk on the market. I would also like to see that at reasonable prices for the measuring range/handheld devices. Sensor resolutions with 384x288 in the B-series and 640x480 in the M-series with lower NetD at the same current prices are overdue.

Or am I asking too much?  ::)

No basically it's the same unit and the same temp. range and the same resolution. The Pocket2 is smaller and thats why I use that one. I can have a Pocket2 always with me in my laptop bag...

Would be great. But when you look back a few years you will see that affordable thermal imaging has come quite a long way from Flukes VT02 to a B20 or Pocket2! But I hope also it will progress and a Pocket2 / B20 with 384x288 would be really great!

I was thinking of getting one of these. I couldn't see any reference in the thread as to how well this imager works with PCBs (checking for thermal issues of course). Does it focus close enough?

I tried a Bosch one a few years ago but it was clearly really designed for use at the room/building scale rather than close up.

Thanks!

Not without a closeup-lens (50.8mm ZnSe lens for a lasercutter). But with such an inexpensive lens and a 3D-printed addon (https://www.thingiverse.com/thing:5397821) you get nice results...

Without you can get an Idea but pinpoint a issue may be difficult. That a image from a B20 without the adapter.

What I have to complain: It would be better if the images were in PNG format. Then there would be no compression loss since PNG is a lossless format.

The JPEGs are radiometric - so they contain all measured values and the software can alter and analyse and newly render them als needed. So consider a radiometric JPEG as something like a RAW image.
The images are also upscaled to 640x480 so even PNG would not loop perfectly fine.

As far as I know it would be also more challenging to add the radiometric data into the PNG header but I have not looked so detailed into PNG and into JPEG.

Thats true. But then you always have the need to forcibly load the photos into the software. The photos as they come out of the camera are often sufficient enough without tweaking afterwards. If you then have compression artifacts (which you would also have after saving them with the software) it doesn't look so nice - e.g. for reports.

I received this interesting "toy" only a few days ago and the device, overall, seems to work very well.

On my unit, I noticed the following firmware anomaly: regardless of the humidity value set on the thermographic settings, the humidity value obtained by recalling the info field of the taken photos is always equal to 60%. All other thermographic parameters are reported correctly (i.e as setted).

Has anyone noticed this bug?

Many thanks!

In the meantime, the doubt I have is: which humidity value is used by the device to calculate the temperatures, the one in the "settings" menu or the one shown in the "info" field of the images?
May be that the answer to this question could come from the Analyzer software. Anyway, the sensivity to this parameter should be very low...

I can't tell you that but I have used Flir Thermal Tools where I am pretty confident all calclulations are correctly.
I set the distance to 30m because the humidity is used to compensate for water in the air blocking IR radiation. The difference between 10% and 90% rel. humidity is the difference between 13.5 and 13.6°C!
With a distance of 300m the difference between 10% and 90% rel. humidity is the difference between 12.9 and 13.5°C...

So there is a difference but it's very minor and not important in normal applications. This factor become more important when the distance to the subject get bigger. It also "just" effect the temp. calculation but not the visual representation. I hope that put at least the importance of that factor into perspective.

For those temperatures that may be the case.  However when running around 25°C and 30 - 80% RH there is a bigger difference.  Even setting up cameras at 4m (BST cores, for a set output signal to represent a 5°C difference) there was a significant difference 4pm to 8am, 10% of signal.
It went away close up, so was air absorption, not simply the chart 20-25 becoming 25-30 °C as the day warmed up.

I tryed it in Thermal Studio with an object which is ca. 28°C warm.
I set 30m distance and 10%RH vs. 90%RH was resulting in 28.4°C vs. 28.7°C. The same with 300m distance resulted in 28.8°C vs. 29.9°C.
To reach the +/- 5°C between 10% and 90%RH I have to set a distrance of 1400m!

In these days I have had the opportunity to test the Hikmicro Analyzer software.
I find that it has a good structure but at the same time it lacks of many basic functions some of which I have already had the opportunity to report to the company support (without receiving any feedback about it...).

Below, what I observed regarding this SW:

1) In "Image Analysis" the "PIP" Display Mode lacks the possibility to resize te PIP frame

2) More, the same "PIP" Display Mode lacks the possibility to remove the "Fusion" effect from the thermal image frame (in order to have a pure thermal image on it).
This aspect also concerns the firmware of the thermal imaging camera (Pocket 2). Even in this enviroment, it would be nice to have the possibility to remove the fusion effect

3) A big problem also affects the three panes on the right side of the Image Analysis window (named "Image Information, Measurements and Parameters respectively). If you try to scroll with the mouse wheel on these windows, if the pointer is above one of the many parameters present, the relative value will inevitably be altered!!!.
You can do enormous damage, even without realizing it, simply by rolling the mouse wheel!
Incredible the fact that none of the development team has noticed this obvious criticality!!!
More, once this damage is done, there's no going back. You have to start from the beginning, reloading the image.

4) Another incredible lack affects the "Report Editing Page". If you try to resize any image, you will lose its aspect ratio!!
There is no way to preserve the image ratio nor to recover it!

It is my opinion that nobody from the development team has ever deeply tested this software...
A software full of gaps and which contrasts with the excellent firmware of the Pocket 2 camera.

Is anyone able to tell me some valid alternative SW dedicated to the analysis of thermal images?

There is none. If you test the software of Guide or even Infiray they are much worse. Infiray alter for example dates and other Information on the image and Guides Software don't even factor in changes in RAT or emissivity afterwards, etc.

There is nothing better that's why I tell always there is no other cineese brand you can use for prof. work except Hikmicro. The Software works at least and you can get alon these issues. At least you get correct results out of the software which (as sad as it sounds) is the best you can expect if you don't go with Flir, Fluke or Testo...

If you want better Software you have to go with an Flir E6 and pay 4x more or you go with a Testo 868s and hope the Super-Resolution will give you the same image quality as native 256x192 or you go with a Testo 871s and pay 4x more and not just 2x more.

Thanks a lot!

I'll try again to report to Hikmicro these lacks / criticalities, hopefully they will be fixed in an upcoming software release...

Question: can the images produced by the Hikmicro Pocket 2 be loaded and processed by the starter version of Flir Thermal Studio or are they incompatible with it?

I have 4 different cameras and there I have to use 4 different programs. No file-format of any camera can be edited in another software theeen the manufactorers one. Some manufactorers like Uni-T and Infiray have even different software for different cameras!

So the answer is no. All manufactorers use prop. formats.

There are some advanced reporting tools but as SaaS offering and you have to pay some money per month: https://ti-reporter.com/

I can even help you more - if you want I can send you a few sample-images grom Guide and Infiray. After trying there software you will be really happy with what you have  :-DD

If you want to try other chineese reporting tools send me your email address as PM.

@markb1980

How did you add the Pocket 2 camera to HIKMICRO Studio?
When i add a device, the mask attached is opened - however, what port number, user-name and password do i have to enter?

I am not sure you can do that. Studio is as far as I know for the network / fix installed cameras
