PPM2 Portable Trace Moisture Analyzer
Portable, battery powered, trace moisture analyzer designed for monitoring moisture levels
The Edgetech Instruments Model PPM2 is a portable battery powered trace moisture analyzer designed specifically for monitoring moisture levels in dew point 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 fundamental measurement of the moisture present. The PPM2 is ideally used in relatively clean, dry, inert gas applications.
