137 Vigilant Aircraft Hygrometer

The Edgetech Instruments Model 137 Vigilant Aircraft Hygrometer is a rugged, shock mounted military qualified instrument used for the primary measurement of dewpoint in flight or in installations with existing flow, such as wind tunnels. It features a miniature remote dewpoint sensor employing a platinum resistance thermometer, and has 15 feet of interconnecting cable to the control unit. Precision calibration …

ELH Series – Precision Humidity Chambers

The Edgetech Instruments Model ELH Series is a series of precision humidity chambers, with NIST traceable accuracies in humidity (±0.5% typical), temperature (±0.1°C) and dewpoint (±0.2°C). The ELH Series consist of a programmable controller for constant precision control and uniformity, and an integrated DewMaster chilled mirror hygrometer for accurate temperature and humidity measurements. The ELH series offers three standard chamber …

DewGen – High Accuracy Dewpoint Generator

The Edgetech Instruments Model DewGen is a divided flow dewpoint generator that can generate dewpoints from +15°C to frost points of -80°C. The source gas is typically dry nitrogen and can be used as a stand-alone or used with an Edgetech Instruments Model DewMaster with an S3 chilled mirror dewpoint sensor resulting in a very accurate, NIST traceable calibration system. …

DPM-99 Dewpoint Monitor

The NFPA 99 has mandated that for Med Gas systems the “dewpoint for locally compressed air shall be monitored and alarmed per 4-3.1.9.8 and 4-3.1.1.2(f) to protect from line pressure dewpoint rise to 39 degrees F (3.9 degrees C) from a nominal design of 35 degrees F (1.7 degrees C).” This safeguard was the foundation for the new Edgetech Instruments …
