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

There are many types of devices used as cryometers:

  1. thermocouples: these can be used down to measure about 1 K temperature.
  2. vapour pressure thermometers: these can be used to measure temperatures down to about 0.5K
  3. resistance thermometers: these can be used to measure temperatures at 0.01 K.
  4. melting curve thermometers: these can be used to measure temperatures between about 0.001K and 0.5K
  5. resistance noise thermometers: these can be used to down to about 0.001K
  6. magnetic thermometers: which are used at 0.001 K temperatures.
  7. nuclear-resonance thermometers: these are required to measure very low temperatures such as 0.0000001 K.
