Keysight U5855A TrueIR thermal imager

[Kilrah]

I have just asked for a quote on a TE-Q1 Plus

Surprised you don't already have one of these 

I have the Q1 with both lenses i.e. the 6.9 from the "normal" one and the 13mm from the "Plus". I took the above with the 13mm which is a tad wider than what's on the U5855A.
The app is a bit meh, but the imager in itself is very good as you can see. Temp range a bit small at 150°C max but that still covers quite a lot of frequent uses in electronics.

Someone needs to make a better app

[TheSteve]

The TE images do look great, but at the same time prove a lower res sensor gets the job done.

I've been amazed at how well I can see birds flying off in the distance when playing with my camera outdoors in the evenings while walking my monster cat.

[Kilrah]

For sure the keysight gets the job done, and better as I said due to the convenience of controls, calibration of temp readings that should be significantly more accurate and much wider temp range - that's why I got it.
However if you're after the beauty of thermal imaging - no comparison.

The point is probably rather that their "image stacking process giving out 320x240 equivalent" is mostly a marketing gimmick as expected

Freaking cold wave these days after having spent a week in shorts, so I'm not going to do more than shoot from my window

Anybody know what DC barrel jack is used for the power?

Thanks!

The DC charger needs to be a 12V 3A with a standard 2.1mm connector and positive in the center

[Kilrah]

Nope, 2.5mm

[TheSteve]

I'm pretty confident it is 2.1mm. That is right from the data sheet of the included power adapter, which is a DVE DSA-42D-12

[Kilrah]

Well reality wins - my 2.1mm adapters don't fit in, the 2.5mm ones do

Could be different versions as well but it would be slightly surprising.

[TheSteve]

I would think then there are a few versions of the power adapter. Tough to argue with reality

[nfmax]

Tough to argue with reality

No, on the contrary: it's easy to argue with reality - just difficult to win

I received mine this morning, no battery yet  , but I had a power adapter that works.
Updated the firmware without problem and took a couple quick comparison photo to the Seek Compact Pro

The Seek is pretty disappointing in my opinion.

Here's a comparison photo, the Keysight on the top and the Seek on the bottom.



Will be a lot happier when I'm able to get my hands on a battery, but I'll be testing this out a lot before then.

Well, it's here at last! DHL attempted delivery yesterday while I was out (naturally). I collected it from the delivery point today, but I've only had the briefest chance to play with it this evening. So far, so good. However, I need to spend a few hours with the manual, learning how to drive it properly, before I pass judgement. One thing leapt out at me though - getting the focus right makes a big difference. The unit itself seems to be in brand new condition, although with Agilent branding.
 

[chili_red]

Mine also arrived looking brand new, very pleased with the condition of the unit itself.

Completely agree about the manual focus, and it seems very touchy but easy to adjust, Seeks focus adjustment is less sensitive.

[onesixright]

One thing leapt out at me though - getting the focus right makes a big difference.

Difference in what if I may ask? In focus (image sharpness), temperature or both?

[nfmax]

Both. If the focus is way out you get a screenful of meaningless blobs, but the difference between 'almost right' and 'right' makes a significant difference in sharpness of temperature contrasts, showing up small hot & cold features. In turn, this causes the displayed temperature range to scale to accomodate them, reducing the visible noise.
I took some images of the woodburning stove last night (the evenings are still cold enough, I reckon) which look great, really sharp, with a maximum indicated temperature of around 260 °C. Unfortunately, I discovered all the spare memory cards I have knocking about here are mini-SD, not SD, so I can't post a picture.

I've just joined the club. I've bought one with a new battery but no other accessories. Perhaps they realised that batteries are hard to come by - the only place I can see that has them (batteries) in stock in the UK seems to be Conrad and they want £107 including VAT and postage so I was pleased that Keysight/Agillent are supplying one.

I now need to order a charger and perhaps a new SD card though I have one in my normal camera I could use.

[Fraser]

Well done.

Yes I see that they have increased the price, but now include a battery.
I spoke with the chap dealing with the sLe of these cameras regarding the lack of a battery. You could not meet a nicer guy. I understand that he has the job of selling a quantity of these cameras but once they are sold, there will be no more. It is a finite stock holding for a specific purpose that is no longer required.

It seems I got really lucky picking up the last battery from RS at only £55!

This sort of thing does not normally happen to me

[chili_red]

Something I noticed upon close examination, the lens was extremely dirty, big smear across it and some what looks like storage dust on it.
After cleaning with a lens swab the pictures came out even better looking "providing they were in focus".
For a Macro picture it came out good, a lot more detail than what I expected.

[HighVoltage]

My battery arrived today from datatec (German Keysight distributor)
Interestingly the battery is almost completely empty and needs to be charged first.

[Fraser]

Old stock ?

I would expect the new battery to have approx half charge upon receipt.

Does the battery have a build date on it ?

Fraser

[Marioka]

Hi.
I bought a U5855A with out battery.
Distributor informed me to wait 2 months for U5752A battery.
OMG.

[Fraser]

Just heard from Keysight regarding the battery charge situation.

The batteries are deliberately discharged to almost 'empty' prior to shipping due to airline requirements.

It is therefore normal for the battery to be received in a discharged state and they are not old stock.

Thank you, this clears it up and it makes sense.
My battery charged over night in the U5855A and this morning was fully charged and works great so far.

[Kilrah]

Yes this has been the norm for RC lipos and such since a few months as well, they discharge them to <30% before shipping instead of leaving them at 60% storage charge.
