Looks to be working OK. That appears to be the imagery of the standard Seek Pro J3-603-320 OEM core.

Check the temperature measurement accuracy...... it is an area that can be an issue with the J3-603 core.

Hi
I forgotten to mention that the Cam have an replaceable Accu to. The is in the Handle. The "only" Downside is the use some special Connector and maybe is not that easy to get.
I just use them as expensive Toy. How should I measure it?

Basic thermal camera measurement accuracy tests.....

Set the Emissivity to 0.96 for Ice water and Ambient water

Measure water with lots of melting ice in it. Result should be close to 0C
Measure boiling water in a pan or kettle. Result should be close to 100C
Measure a non reflective surface with a thermometer and then measure it with the camera. Compare results. Emissivity does need to be considered for the imaged surface.

Hello. Excuse my bad english.
in my country I cannot find the answer to my question. I have an Hti-HT19 and Hti HT-A2 thermal imager.
Very good appliances. But I miss setting the temperature range. For example, from + 5 to + 15C.
Is there a possibility of a new firmware of the device?

 :-+ I dont see any Updates. I dont know if its possible for us "end user" to do so.
Maybe there are some hidden Pins unprotected against a Hack.

I got the Hti HT-A2 and I recommend it to anyone who can afford it!

I managed to ask the seller on aliexpress to do a 50$ invoice => No import fees  :)

My version of firmware is 2.1.8
