HP125 Series Relative Humidity Probe
Measure 4 Parameters with One Probe Simultaneously captures RH%, temperature, dew/frost point, and pressure (absolute or barometric). No Downtime for Recalibration Replace the smart sensor tip in seconds—each is pre-calibrated and ships with a NIST-traceable certificate. Built for Real-World Use Designed for in-situ measurements in compressed air systems, labs, and environmental testing setups. Modular & Flexible Works as a standalone …
DPS3 Heated Dewpoint System
The Edgetech Instruments DPS Series is a heated dewpoint hygrometer that can measure dewpoints up to 95 °C (203°F) and as low as -35 °C (-31°F). This integrated system includes a microprocessor based electronics, a chilled mirror dewpoint sensor, a sample flow meter/valve, assorted tubing and fittings all contained in a heated, temperature controlled NEMA-4 enclosure. The DPS Series heated …
Features
- 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.
- Automatic Balance Control mode provides correction for optics contaminants
- Integrated DPS system contained in a NEMA-4 enclosure with alarm relays and continuous digital and analog outputs
- Three models available, the DPS3 stand-alone, DPS4 with pressure compensation and the DPS5 with external DewMaster Hygrometer
CAM Compressed Air Module
The CAM (Compressed Air Module) is a sampling chamber for use with Edgetech Instruments humidity and dewpoint probes. It has a sample inlet ball valve for connection to a pressurized compressed air or gas takeoff point, providing an easy way to connect a probe or alarm module to a gas supply. The ball valve allows isolation of the probe from …
Features
- 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
- May be used for pressure dewpoint or atmospheric dewpoint measurements
- Available in brass or stainless steel construction
