What Edgetech Instruments does

Edgetech Instruments Inc. is a privately held manufacturer of precision moisture and oxygen measurement instruments headquartered at 399 River Road, Hudson, Massachusetts. Founded in 1959, the company designs and builds chilled mirror hygrometers, dew point and humidity transmitters, oxygen analyzers and transmitters, portable field units, calibration equipment, and supporting accessories (sensors, probes, sample modules). The core technology is the chilled mirror hygrometer, which Edgetech identifies as its invention: a primary dew/frost point measurement method using photo-optical detection of condensation on a temperature-controlled mirrored surface, complemented by secondary sensor modalities including phosphorus pentoxide (P2O5) electrolytic cells for trace ppm moisture, aluminum oxide capacitive sensors, polymer RH probes, and galvanic fuel cells for oxygen. Proprietary technologies include the chemically resistant X3 sensor with minimized sample cavity, novel ice nucleation in the DewTrace system, Automatic Balance Control (ABC), and a patented variable capacitance pressure sensor.

The company serves a diverse set of regulated and quality-driven end markets through vertical specialists, including pharmaceutical and medical gas (NFPA 99) applications, semiconductor cleanroom and process gas monitoring, aerospace and defense (including the military-qualified Vigilant aircraft hygrometer), compressed air and industrial gas (ISO 8573-1), automotive and engine testing (ASTM MON/RON), energy and battery manufacturing, HVAC, and metrology and calibration laboratories. The product portfolio spans lab-grade bench units (DewMaster, DewTrace, DewTech 390), process/oem transmitters (DewTrak II, 6742/6744), portable field units (Model 1500, PDM75-X3SF, AM560/AM560-SS), oxygen analyzers (AM507, OxyTrans family), alarm modules (SENTRY, DPM-99), and calibration/support equipment (RH CAL, ELH chambers, DewGen).

Revenue is generated through four streams: hardware sales (instruments, replacement sensors, and subassemblies for both Edgetech and competitor chilled mirror instruments), ISO/IEC 17025:2017 accredited calibration and certification services with NIST traceability, an instrument rental and leasing program, and aftermarket sensor and parts replacement. Most sales run through a direct enterprise motion supported by a website "Request a Quote / Application Support" form and a network of regional manufacturers' representatives (e.g., Allesco covering Gulf Coast and Mid-Western US states). Pricing is largely quote-based, with starting prices disclosed at $2,150 (AM507 inline oxygen analyzer) and $5,450 (PPM1 trace moisture analyzer). The company holds ISO 9001:2015, ISO/IEC 17025:2017, NIST traceability, and ATEX certifications, and states 65+ years of continuous operation, 1-10 employees, and a global customer base anchored in the United States.
