content: Hi,Just started with thermal imagingGot a used Cat S62 Pro from eBay for a good price. This phone has the Lepton 3.5 sensor, which I guess is comparable to the one used in the Flir One Pro.Unfraternally it seems that only the software that comes with the phone (MyFLIR 3.0.55) can access the thermal camera, so I can't really use any other apps...I've searched a bit, and it seems that you can't get the Therm-App Pro module anymore, which is a shame, since it's probably the best module for a smartphone (640x-480 resolution, 25Hz), so I thought about getting the HTI HT-301, which has decent resolution of 384x288 and smooth 25Hz.Any recommendation / suggestions?Thanks in advance!

content: Thanks, I couldn't really find what the differences between InfiRay T3S and HTI HT-301 - seems like the hardware is identical and even both official apps work on both models?

content: I bought the HT-19 handheld imager. The only thing I do not like is it always auto ranges so you will always see the full color range on the screen. I'm not sure if this model allows manual ranging but that is something I would look for next time.
