Cryometer
 | This article relies largely or entirely on a single source. (September 2019) |
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 0.5K
- resistance thermometers: these can be used to measure temperatures at 0.01 K.
- melting curve thermometers: these can be used to measure temperatures between about 0.001K and 0.5K
- resistance noise thermometers: these can be used to down to about 0.001K
- magnetic thermometers: which are used at 0.001 K temperatures.
- nuclear-resonance thermometers: these are required to measure very low temperatures such as 0.0000001 K.
