Overview
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...
DPS3 Heated Dewpoint System
- Heated dewpoint hygrometer system for measuring dewpoints up to +95°C in high dewpoint gases
- Solves the high dewpoint measurement problem by heating all system components to a temperature above the dewpoint temperature of the sampled gas, preventing condensation in the measurement system
- Chilled mirror sensor provides high accuracy over the entire dew/frost range of +95°C to -35°C.
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...
SENTRY Compressed Air Monitor and Alarm
- Detects upset conditions in compressed air systems
- Constantly monitors pressure and dew/frost point temperature
- Strobe lamp and pulsing audible alarms for low pressure or high dew/frost point alert
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
CAM Compressed Air Module
- Sample chamber allows safe isolation and servicing of sensor probe at pressurized sample takeoff point
- For installation and use with HP125 and Sentry humidity probes
- Provides ball valve to isolate probe from process pressure and bleeder valve to allow flow of sample gas past the probe sensor
