Scientific Instruments, Inc.

Scientific Instruments, Inc. was founded in 1967 by aeronautical engineer Jack Hoey and low temperature physicist Gilbert Halverson. Coming from aerospace and academic backgrounds, they saw a market need for cryogenic temperature measurement and developed one of the first Germanium Resistance Thermometers (GRT) and supplied these devices for use on the Apollo Lunar Program. Today, Scientific Instruments, Inc is owned and operated by founder Jack’s daughter, Leigh Ann Hoey. An ISO 9001 certified company, Scientific Instruments is involved in the design and manufacturing of cryogenic temperature sensors for laboratory, industrial and medical applications, temperature indicators and controllers, petrochemical tank gauging systems for liquid natural gas (LNG) Storage tanks, and FAA-PMA certified temperature probes for commercial aircraft.
