Overview
RH CAL Relative Humidity Calibrator
The RH CAL Relative Humidity Calibrator from Edgetech Instruments is a microprocessor‑based, programmable humidity calibration system designed for both metrology laboratories and on‑site field calibration. Unlike conventional humidity calibration systems, the RH CAL is entirely self‑sufficient, requiring no compressed air or water connection, making it a truly portable relative humidity calibrator. Using...
PDM75-X3SF Portable Dewpoint Hygrometer
The Edgetech Instruments PDM75-X3SF is a rugged, portable dewpoint hygrometer engineered for industrial field use where accuracy, durability, and NIST traceability matter. Built around a primary-method, chemically resistant chilled mirror dew/frost point sensor, the PDM75-X3SF delivers drift-free accuracy, low maintenance, and reliable performance in a high-impact portable case. The system...
DewTech 390 Low Dew Point Hygrometer
The Edgetech Instruments DewTech 390 is a high-precision, laboratory-grade hygrometer system engineered for demanding low dew point measurement applications. Designed for use in metrology labs, research settings, and high-performance industrial environments, it leverages a primary method, three-stage Peltier-cooled chilled mirror sensor to deliver highly accurate, direct dew/frost point readings from...
HP125 Series Relative Humidity Probe
The HP125 Series from Edgetech Instruments is a next-generation relative humidity probe designed for portable on-site measurements in industrial and laboratory environments. It continuously monitors up to four key environmental parameters—relative humidity, temperature, dew/frost point, and pressure—using a smart sensor tip that simplifies calibration and maintenance. Unlike typical temperature and...
Vigilant Aircraft Hygrometer
- A rugged, shock mounted dewpoint hygrometer for in-flight and wind tunnels
- Uses a primary method chilled mirror dew/frost point sensor for high measurement accuracy

DewTrak II MO for Motor Octane Testing
- NIST traceable chilled mirror hygrometer continuously monitors motor intake air fuel mix conditions required for Motor Octane Number (MON) and Research Octane Number (RON) testing
- Monitors specific humidity and barometric pressure for compliance with test standards ASTM D2700, D2699, D2885
- Can be easily fitted to existing knock engine systems
ELH Series – Precision Humidity Chambers
- A group of precision calibration chambers incorporating programmable controllers plus primary method DewMaster chilled mirror hygrometers
- Highly accurate temperature and humidity control similar in performance to two-pressure method devices but at a significantly lower price
- Delivered with multi-point, NIST traceable, ISO/IEC 17025 accredited certification
Model X3 Chilled Mirror Hygrometer Sensor
- Chemically resistant sensor housing and mirror eliminate sensor failures when measuring dew/frost point in aggressive background gases
- Chamber design and high efficiency heat exchanger result in the ability to measure very low frost points
- Hinged cover plate allows easy access to the mirror for cleaning and inspection
