The 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.
