Question

Which thermometer(s) can be used for
measuring temperature of 60 K ?

Answer 1

A cryometer is a thermometer used to measure very low temperatures of objects.

There are many types of devices used as cryometers:

• thermocouples: these can be used down to measure about 1 K temperature;
• vapour pressure thermometers: these can be used to measure temperatures down to about 0.5 K;
• resistance thermometers: these can be used to measure temperatures at 0.01 K.
