About Us

Our Story

Edgetech Instruments Inc. traces its history back to 1965, when it began operating as a part of EG&G using the ideas and inventions of Dr. Harold E. Edgerton. Not long after this group began functioning, EG&G decided to expand its involvement in the instrumentation market and acquired Geodyne Corporation (marine products) and Cambridge Systems (atmospheric products), creating the EG&G Environmental Equipment Division. It was Dr. Edgerton, and his tireless efforts to build better technological solutions to problems, that inspired the “EdgeTech” name, honoring him and driving the company with a commitment to remain at the leading edge of technologies in the markets served.

Edgetech Instruments Inc. came under new ownership and management in 2014, moving to a modern new facility in Hudson, Massachusetts, USA.  Edgetech Instruments manufactures highly reliable, state-of-the-art instruments, which deliver unprecedented value and world-class performance. These qualities assist our customers to outperform their competitors and compete successfully in their markets. Currently, Edgetech Instruments focuses on trace moisture, relative humidity, and oxygen measurement, utilizing varying technologies. At the heart of our business is the chilled mirror technology, which gives unrivalled accuracy in the measurement of trace moisture. Our facilities are ISO 9001:2015 registered. We have built a state-of-the-art calibration lab which is ISO/IEC 17025:2017 accredited where we calibrate not only Edgetech Instruments but also other brands of moisture, temperature, and oxygen instrumentation. Edgetech Instruments manufactures in the US, but is a global company with authorized representatives and agents located in major countries around the world.


Since its formation in 1965, Edgetech has built a reputation as a trusted partner in the supply of the highest quality of humidity, moisture, and oxygen solutions available on the market. The key to the company’s success has been an unwavering and ongoing commitment to customer support and satisfaction.
