Model PPM1 Trace Moisture Analyzer
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 electrochemical
(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.
 Applications Include
• Electric Power (Transformer Gas)
• Common Process Gases (Semiconductor Industry)
• Pharmaceutical Industry (Medical Gas)
• Gas Supplier Industry (Quality Control)
Fea t ures
• Sensitivity below 1ppm
• Fast response
• Long sensor life
• Low cost
• Fundamental measurement of moisture content
• Displays / outputs—dew point (C/F) and PPM values
