Having gained a smidgen of experience melting ABS plastic resin, I was seeing unexpectedly high temps from the display. Thinking that perhaps the readings might be off, I decided to hunt down a suitable temperature probe. I found one. It is calibrated and reads up to 300C +/- 1 degree.

It’s a TRACEABLE - Kangaroo Thermometer made by Control Company and purchased through Scientifics Direct DBA EdmondScientific for ~$35+S&H.

At that price, it doesn’t seem very sturdy, but if it works as claimed, what a bargain. The purchasing process was less than wonderful - but I did get it in an otherwise timely fashion. What a terrible process. The customer service guy was cool but their system misses the mark.

I will be able to stick a probe on the hot-end or the bed and know what its temp is. I had a laser heat gun - but I didn’t like the weird readings I got. So i’m going to have to test it this weekend.

The laser/ IR thermometers need to be calibrated for the emissivity of the material you are measuring the temperature on.

That’s the first time I had heard that. And now that I looked up what that means, I guess it makes a good bit of sense. I was aiming at relatively clean brass. I did try to get as close as I could, but the extrusion nozzle is centered slightly behind a somewhat smaller hole in a wooden board. So I knew the cone of accuracy would come in to play but didn’t think about how it being shinny and bright would also affect the readings.
