Cryogenic Temperature Measurement: Cryogenic Instruments and Probes

Scientific Instruments Cryogenic Temperature Measurement

The initial products developed and manufactured by Scientific Instruments were cryogenic instruments such as cryogenic temperature sensors including Germanium Resistance thermometers and Silicon Diodes. These temperature sensing devices created opportunities in the aerospace, industrial and laboratory research industries. Of particular note is the fact that SII supplied a number of Germanium Resistance thermometers that were installed into Helium and Hydrogen systems on the Apollo space craft and at the end of the 1960’s flew on lunar landing missions.

Scientific Instruments Product Areas

The company presently is active in seven distinct product areas, although separate; these products are “synergistic” as they are technologically related to temperature and liquid level measurement and control. With one exception, all product areas supported by Scientific Instruments are related to cryogenic applications, meaning extremely low temperatures, typically in range of 0.05K to 300.0K (-462.0F to +250.0F).

These scientific instrumentation cryogenic temperature measurement products include various cryogenic instruments:

Cryogenic Instruments cryogenic temperature measurement, cryogenic temperature controllers, lng density, scientific instrumentation, how to measure natural gas, commercial cryogenic sensors
