I was thinking of you when I saw this post GSS, was thinking this is was the post you were referring to. It's a great post, hope he continues to post more, as he mentioned. Love to see more of these videos. Go Ricker!

I sure will!!! Only thing I need is more TIME! I wished I made enough selling diodes and handhelds to where I didn't need a full time job!

I wonder if DTR is only selling laser parts or whether he has another job? Anyone know?

This FLIR camera is something I'd love to have too, someday!

I don't know how accurate these are for actually measuring heat at a source. I have heard that precision thermistors work better for this application. They do have that "cool" effect to watch.

Well, FLIR camera's are great tools to find hot spots and such, but also have their limitations.

If you are looking at surfaces like aluminium the termal reading will not be accurate, as they assume 100% thermal emissivity, which is reasonable for many materials, but not shiny ones like metal surfaces.

One trick to read accurate temperatures on metal surfaces is to put a small piece of tape onto them, and read the temperature from that. Those plastic materials have good thermal emissivity, and you can use something like eletrical insulating tape you have around just fine.

If you want accurate temperature measurements
then use an accurate Thermometer.
The Thermal cameras are used to quickly show hot
spots an relative surface temperature differences.

Yeah, that's why in a couple videos in my OP I wrapped the Arcane so there were no reflections of metal. And I stated some spots were merely reflections of my body heat. Also using a thermometer gun as the same time to compare, flir was quite close with actual temperature.
