About Extech
Reviewed 2026-07-26
Extech is an active Teledyne FLIR brand of handheld test, measurement, and inspection tools. The catalog spans electrical meters, clamp meters, environmental instruments, sound and light meters, humidity and temperature products, borescopes, calibrators, and data loggers used by technicians, tradespeople, laboratories, and maintenance teams.
History
Extech began in 1971 and built a broad catalog of portable instruments for electrical, mechanical, environmental, safety, and facilities work. FLIR Systems acquired Extech in October 2007, and the brand later became part of Teledyne when Teledyne acquired FLIR. Current first-party material continues to describe Extech as a brand and integrates its online product information with Teledyne FLIR.
Two events sometimes inferred from abbreviated histories are not part of Extech's corporate identity. FLIR sold the separate Extech Data Systems portable-printer division in 2009; it did not dissolve that division. In 2011 Extech relocated to Nashua, New Hampshire; the move was not a company rename. Neither event changes the identity of the handheld-instrument brand attached to the manuals in this archive.
