In the 1970’s our co-founder, Jack Hoey, negotiated a partnership with Eastern Airlines. Through this Scientific Instruments began manufacturing FAA regulated PMA aircraft parts for commercial aircraft. Revolving primarily around temperature measurement, these probes were based off identicality of OEM parts.

Today, Scientific Instruments supports major commercial airliners with temperature probes for Airbus aircraft’s along with several other primary aircraft platforms around the globe. SI utilizes its vast experience in temperature measurement to produce these highly reliable FAA approved PMA probes. Some of most popular models include the B7110, B7170, B7180, B7280, B7300, and B7320.
