Calibrating Thermometer

[duckmeister]

How I make sure my thermometers are reading correct, just put it up on the A/C thermostat to see how close it reads. This one is right on the money, but usually about 1 in 5 is way off. Years and years this has worked for me.

Interesting method. Not sure I would use it for incubation, as I don't trust the tolerance or accuracy on thermo combos intended primarily for ambient control, but then again I'm a little obsessive. As they say, "It's good enough for government work." Thanks for sharing.
