Make ice cubes out of distilled water. Make a mixture of ice cubes and
distilled liquid water, and shake it up good. When you're sure it's all 32F,
soak the thermometers. the one which reads 32F is correct. The others are
not.

Only an engineer could spend so much time on two degrees.

A friend installed a Honeywell 5+2 Digital Thermostat last weekend.
The inside temperature reads 68 and I am trying to check its accuracy.
I compared it to two free standing digital thermometers which I
balanced on top of the thermostat (at the same time).
The thermometers readings range from 69 and 71; to 71 and 71.
Any suggestions on determining the *right* temperature are
appreciated.

Thank you in advance.
