PPM1Description

The Edgetech Instruments Model PPM1 is a trace moisture analyzer designed specifically for monitoring moisture levels in dew point and PPM units. This trace moisture analyzer utilizes an electro-chemical (P205) sensor in combination with a proprietary semi permeable diffusion membrane.

The principle of operation applies the Faraday’s Law of Electrolysis which measures the dissociation current making it a fundamental measurement of the moisture present. The PPM1 is ideally used in relatively clean, dry, inert gas applications.

WHAT YOU GET:  Model PPM1  Diffusion Cell Trace Moisture Analyzer, complete with Phosphorous Pentoxide (P2O5), Electrolytic Sensor with an operating range from 0.1 to 1250 PPMv, (dew point range -20°C to -95°C). Standard sensor assembly is mounted remote from analyzer module and features a flow through 316SS sample chamber with ¼” compression fittings and 6 feet of interconnecting sensor cable. The Control Module features a 2-line display for both PPM and Dew Point, 2 analog outputs (4-20mA or 0-10VDC voltage), RS232, 2 relay alarms and is housed in an IP65 enclosure. Includes an instruction manual and one year warranty. Unit may be modified in the field to remove the flow through head for diffusion sampling (isolation chambers, glove box, glove bags,…)
