I wonder about those IR thermometers so prevalent
during the past year. Previously, I recall seeing them
at deli salad bars, used to monitor the sour tureens.
I understand the physics, the relationship between
spectrum and temperature. What is the accuracy,
considering the problems of focus and reflection,
and ambient noise?
What's the internal sensor?
It depends on a lot of things, starting with who made the thermometer.
The accuracy also depends on how it is calibrated, as a medical IR
thermometer calibrated for a human forehead will give different results
if pointed at anything else.
The general purpose one I have seems to be calibrated for painted
wallboard and gives different results when pointed at metal wall vents
and human heads.
