Mine is a Extech i5 by Flir. Its a low cost 80 x 80 pixel resolution
Used to be US$2K but now its lower
I suggest you buy this one :
This is a 160 x 120 pixel, better resolution but price still within US$2.5K.
FLIR practically owned the thermal imaging world.
See resolution difference
Since u got so much expensive camera toys, troubleshooting using thermal camera is better than those spot measurement using the other type of infra red thermo gun, which the laser guide dot and the sensor reading area is not that accurate/aligned anyway.
The higher resolution model you choose, you can shoot 1 image from a bit further away and get more data than lower resolution one at same distance.
It will come handy for all cameras asset you got or when you tinker with them.
Have fun shopping David.
