Hello! Has anyone had an issue with classroom thermometers giving different readings? How would you deal with it (especially to get temperature during eclipse)?

1.  Calibrate (ice bath).
2.  Check the specs of the instruments.  That's only +/- ~1/2 degree.
3.  Use it as a lesson for the students:  instruments aren't perfect.  Even when they give you a digital readout to the nearest 10th.

The glass thermometers typically have a 1 -2 degree C range; Depending on what is being measured, I have had more consistent results using the Fluke IR thermometer.

I appreciate the IR thermometer recommendation, and advice to calibrate with an ice bath.
