Temperature Reading and Control


Neocera LTC-21 temperature controllers are used for most measurements. Also, the majority of our probes use Cernox temperature sensors. The sensor calibrations are stored in the temperature controller.

Although difficult to use for precise temperature readings, the pressure readings of the helium-3 and helium-4 baths can be used for a rough temperature approximation. Pressure-temperature conversion charts are taped to the sides of the instrument cabinets.
