Edgetech Instruments, Inc. products

The Vigilant Aircraft Hygrometer is a rugged, shock mounted instrument used for accurate measurement of dew/frost point in flight or in installations with existing flow, such as wind tunnels.

The Edgetech Instruments Com.Air is a rugged, compact dew point monitor engineered for compressed air and gas systems that demand precise and continuous moisture monitoring. Now available with the high-performance X3 chilled mirror dew point sensor, the Com.Air delivers accurate, NIST-traceable, drift-free dew point readings in harsh industrial environments where performance and compliance are critical.

The DewTrace is a high precision, bench top, laboratory standard dew/frost point hygrometer capable of measuring very low frost points using the primary method chilled mirror measurement technique.

The DewMaster Chilled Mirror Hygrometer is a high-performance humidity measurement system designed for environments where accuracy, reliability, and traceability are non-negotiable. Utilizing the chilled mirror hygrometer principle, DewMaster delivers direct, NIST-traceable dew point measurements that meet the rigorous demands of pharmaceutical clean rooms, environmental test chambers, semiconductor fabrication, and aerospace labs.

The DewTrak II MO specific humidity and barometric pressure transmitter is a chilled mirror dewpoint hygrometer that continuously measures the moisture content and barometric pressure in the motor octane testing process. It is used to monitor and ensure compliance with test standards ASTM D2700, D2699, D2885. NIST traceability guarantees measurement compliance for the allowable specific humidity and the pressure ranges.

The ELH Series of precision humidity chambers has NIST traceable accuracies in humidity, temperature and dewpoint. The ELH Series incorporates programmable controllers for constant, precision parameter control and uniformity plus integrated DewMaster chilled mirror hygrometers for accurate temperature and humidity measurements. These highly accurate temperature and humidity control chambers are very similar in performance to two-pressure method devices but they reach soak conditions more rapidly and are significantly more affordable. The ELH series offers three standard chamber sizes: 1.5cu.ft., 6cu.ft. and lOcu.ft. Larger volume chambers are available on request.

The AmO₂xys (AM560) is a handheld oxygen analyzer engineered for portability, accuracy, and versatility. Designed for both trace (PPM) and percent-level oxygen measurement, the AM560 is ideal for field diagnostics, spot checks, and portable gas sampling in diverse industrial and lab applications.

The AmO₂xys (AM507) is a compact inline oxygen analyzer designed for continuous, real-time oxygen measurement in critical gas processes. Supporting both trace (PPM) and percent (0–100%) oxygen ranges, this flexible analyzer is ideal for applications requiring high accuracy, low maintenance, and seamless integration. The AM507 is available in flow-through or KF-40 direct-fit configurations, with output options ranging from basic 2-wire loop power to fully “smart” RS485 Modbus communication.

The Model PDM75-X3 is a field portable dewpoint hygrometer that integrates the accuracy and reliability of the Edgetech Instruments chilled mirror sensor with the convenience and ruggedness required for field use. It features drift-free accuracy, NIST traceability, low maintenance, high durability and ease of use in a portable package. The Model PDM75-X3 has all the standard features of the Edgetech Instruments DewMaster Hygrometer, with a modular chilled mirror sensor that is chemically resistant to background gases. Use it as a field transfer standard, to spot check process gas dryness or to check the calibration accuracy of other hygrometers. The Model PDM75-X3 can be configured for positive pressure sample gas or to extract a gas sample using an integrated vacuum pump.

The PPM1 Trace Moisture Analyzer is a compact, high-accuracy system engineered for measuring parts-per-million (ppm) moisture in gases. Built around an electrolytic phosphorus pentoxide sensor, the PPM1 applies Faraday’s Law of Electrolysis to directly determine water vapor content in gas streams. With a NEMA 4 (IP66/67) enclosure, the PPM1 is ideal for harsh industrial environments and glove box integration. This NIST trace moisture analyzer is made in the USA and backed by ISO 9001 and ISO/IEC 17025 accreditation.
