PPM1 Trace Moisture Analyzer
Trace moisture analyzer designed for monitoring moisture levels in dew point and PPM units
The Edgetech Instruments PPM1 is a trace moisture analyzer for monitoring dew/frost point and ppmV water vapor in gases.
The PPM1 is a modular, remotely mounted hygrometer configured to meet your moisture measurement application requirements.
The PPM1 uses an electrolytic, phosphorus pentoxide sensor in combination with a proprietary semi permeable diffusion membrane. The principle of operation applies Faraday’s Law of Electrolysis to determine the water vapor content by measuring the dissociation current needed to electrolyze the water molecules in the sample.
The PPM1 is packaged in an IP66/67, NEMA 4 plastic enclosure and comes complete with two FORM A relay alarms, two analog current outputs and a RS-232 bi-directional serial interface.
All Edgetech Instruments hygrometers are manufactured and supported in the USA in a modern, ISO 9001:2015 registered, ISO/IEC 17025:2005 accredited facility. All calibrations and certifications are traceable to NIST.
