A new version of the android app has been released (1.7.4)!
For me the gradient is gone .

Major improvement! I wasn't expecting resolution to be improved this much. I can see finer details and objects that used to blend in now stand out

I have an early android unit from october. gradient was terrible. it looks to be gone. im going to test it some more.

a quick test shows temperature readings that appear correct.

EH??? That's fantastic news! My Android SeeK arrives any day, I greatly look forward to testing it with the (already downloaded) 1.4.0 or whatever it is, and the new version.

EDIt--yes i just nipped over Google Play to check (in case it was a hoax!)--1.7.4, released 9th Jan. Woohoo!

EDIT2--Jaybeez, re your edit--excellent!

Update is out for iOS. Absolutely amazing. 100x better. Seek is back in the game.

Excellent improvement in gradient....no gradient showing on my unit. I just did a test with Black body at 42C and a piece of card at ambient. Noise may be higher on card in new version.... Not sure and too late to play. Before and after pictures attached

Wow, they really fixed it.

My gradient is gone as well. I was close to returning mine because I was worried Seek wasn't going to (or couldn't) do anything about it. Nice work!

heavybarrel · « **Reply #1405 on:** January 10, 2015, 02:11:14 am »

I am starting to think that the folks over at seek are busy doing what they need to be doing! I've gotta give them some kudos here, they said they were working on a fix for the gradient issue, appears that was 100% truth. They said after apple stopped being a massive pain in the a** we'd get our devices, we got em! Lets not forget they lost a big player, a very sad event and surely something that would cause disarray. I for one have been very happy with my seek device, even with its issues! it really does all that it is claimed to do, and to see that these guys are making the efforts to get back on the ball are very encouraging! I for one am very impressed and look forward to whats next! A big thanks to the folks over at seek, hopefully they are also thanking the wonderful people here at the eevblog for being more than excited about assisting in any way they can. Gotta love the internet

Awesome news, not too shabby for a new up and coming company.
My camera is still on loan so I can't check if the seeker program works with the new firmware or if there is a new firmware on the latest update.

WS-PI · « **Reply #1407 on:** January 10, 2015, 07:35:08 am »

For me the gradient is also gone complettly but I can not find the settings for emissivity factor. Is it gone too?

Thank you. I was to fast with the upgrade to do it myseft.

Image quality seems to be improved too.

Left (old), right (new).

Yep, it's also gone. But it didn't work anyway, at least my readings didn't change when setting different values.

Fraser · « **Reply #1413 on:** January 10, 2015, 09:34:36 am »

Oooops, a thermal camera with radiometric functionality, without an emissivity setting, now that is novel

What the heck are they thinking, even my cheap IR thermometer offers emissivity setting, its a critical element of IR temperature measurement. They should at least advise users of what emissivity they have chosen as 'one size fits all'. Hopefully it will be 0.96 or 0.97.

Emissivity correction is simple maths for a camera measurement process so this surely must be an error on the part of Seek Thermal. More inadequate/incompetent UAT I wonder ? They really do need to get themselves a decent product tester.

@Aurora

sorry but what is the meaning of the abreviation UAT ?

Seeker · « **Reply #1415 on:** January 10, 2015, 10:48:21 am »

The app size has gone down from 11.33 to 7.6Mb...maybe that's where the emissivity fuctionality went. I wouldn't know what to enter in it anyway, and neither (I suspect) would the majority of users of this device. The fact that the gradient has been eliminated and the temp measurements are close is sufficient, to me. I'm soooo glad I now won't be compelled to dismantle it.
Now wish postie would hurry up and deliver mine...want to see how my urine stream looks, for starters.

I think SeeK could have been a bit more communicative about their efforts to repair the gradient. Some members have virtually devastated their units, thinking they were stuck with the issue.

Who updated the program. Please make a photo palm. I do not have the original lens. I want to see photos from the original Seek. In an attachment photo palm with my lens.

Fraser · « **Reply #1417 on:** January 10, 2015, 10:58:47 am »

UAT = User acceptance testing

The final stage of testing before releasing a new or modified build.

The UAT is supposed to identify any issues that a user may not like...... such as the flippin great temperature gradient on the images, and now no emissivity setting

WS-PI · « **Reply #1418 on:** January 10, 2015, 11:00:49 am »

With the old SW the camera got a little warm after some minutes. With the new SW I could not feel the temperature rising. Even after 10 minutes. Has anybody the same observation? As the firmware was not changed I not sure about my oberservations.

frenky · « **Reply #1419 on:** January 10, 2015, 11:26:19 am »

Photo of my palm... Not to comperable since my palm has 34*C and the background is at 20*C.

Uho · « **Reply #1420 on:** January 10, 2015, 12:36:04 pm »

Thank U. My pyrometer shows 26.6 in the same place. The difference of 1.4 degrees. Palm temperature is the same on both devices. I wanted to see the distribution of heat in the palm. For example, photos done Flir 4. And TV 04 Kst.

Fraser · « **Reply #1421 on:** January 10, 2015, 01:56:39 pm »

My seek is reading 4C low when tested against my accurate (+-0.1C) Black Body. See my previous images. 38C reading on a 42C black body. Also note the 'hotter' area on the right hand side of the Black Body. When checked with the Seek, it also reads 38C

The hotter area does not exist on the black body in real life.

Not that such concerns me as I will never trust the Seek for accurate measurements

As befitting its cost, miniature dongle form and target market. It isn't intended to obsolesce* professional units.

heavybarrel · « **Reply #1423 on:** January 10, 2015, 03:03:10 pm »

The emissivity settings have been gone for quite some time, i mentioned it in a previous post. If i had to guess,,,,, the settings were no good so seek just removed them until they can make them work correctly. I think this is one of those "hang in there" moments. I might be crazy here but, it seems like the shutter is operating faster than before the new update. I remember the steady somewhat slow click because i played with the camera for hours. Whatever wizardry has been done in the software has totally removed the gradient from my device and the spot tracking also seems much faster. Cant wait for the next update!!

tom66 · « **Reply #1424 on:** January 10, 2015, 03:30:57 pm »

It has been suspected some of the gradient was caused by heat near the sensor. Maybe they just found a way to make the processor run cooler (optimising the code, underclocking, etc. who knows) thus virtually/completely eliminating the issue.

Now I have to get me one of these, damn it!
