Cryogenic Temperature Measurement, Cryogenic Temperature Controller, Commercial Cryogenic Sensors

The initial products developed and manufactured by Scientific Instruments were 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.

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:

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

Model SI-7000 LTD Tank Gauging System

All New For 2016!

We proudly introduce – after 40 years of delivering the world's most trusted LNG tank-top LTD systems – the completely reimagined, redesigned, and most advanced solution for LNG tank profiling: The Scientific Instruments Model SI-7000 LTD.

Cryogenic Temperature Probes

The Series 44 Temperature Probes are constructed of stainless steel and are hermetically sealed units allowing for installation into hazardous environments.

Raman Gas Analyzer System

The Raman Gas Analyzer System promises to change the way natural gas is measured. Raman spectroscopy is an indispensable tool for buyers and sellers interested in managing monetary risk as well as for process managers desiring to increase production efficiencies.

Model SCM10

The Scientific Instruments, single-channel Model SCM-10 Temperature Monitor provides the accuracy, resolution, and interface features of a benchtop temperature monitor in an easy to use, easily integrated, compact instrument.

Model 9302/9304/9308

With two or four input channels with ethernet connectivity, these models are the most flexible and accurate temperature monitors currently available.
