Introductory Video to Model 459 Cryostat
Our latest introductory video introduces the Model 459 Cryostat – take a look to see how we can calibrate in the range -80°C to -180°C
In addition to the cryostat, we have other solutions for low temperature calibration
Calibration at -196°C
Liquid Nitrogen has a boiling point of about -195.8°C, it is relatively easy to obtain and allows thermometers to be calibrated by comparison. Liquid Nitrogen can be added to a suitable calibrator to provide the “cooling” and thermometers under test can be compared to a calibrated standard.
Stirred Liquid Baths
Stirred liquid baths can be used to calibrate at low temperatures, but they cannot cool to as low as -195.8°C, most baths are limited to around -80°C.
