The Edgetech Instruments DewTech 390 is a precision dew/frost point hygrometer that measures extremely low frost points or trace moisture in a variety of background gases. Based on the primary method chilled mirror sensor technique, it is delivered with a NIST traceable calibration certificate and is certified in an ISO/IEC 17025 accredited calibration laboratory. At the core of the DewTech …
PPM1 Trace Moisture Analyzer
The PPM1 uses an electrolytic, phosphorus pentoxide sensor in combination with a proprietary semipermeable diffusion membrane to measure trace moisture as parts per million by volume (ppmv) water vapor or dew/frost point in dry inert gases. The PPM1 is modular and may be mounted remotely. It is packaged in an IP66/67, NEMA 4 enclosure and comes complete with two FORM …
PPM2 Portable Trace Moisture Transmitter
The Edgetech Instruments Model PPM2 is a portable battery powered trace moisture analyzer designed specifically for monitoring moisture levels in dewpoint and ppm units. This trace moisture analyzer utilizes an electrochemical (P2O5) sensor in combination with a proprietary semi permeable diffusion membrane. The principal of operation applies the Faraday’s Law of Electrolysis which measures the dissociation current making it a …
