Air-Dry Moisture Analyzers are suitable for most gas and some liquid applications. They are available in several configurations to provide a calibrated read out in any or all of the following units from a single analyzer:
Dew Point in °C or °F
PPM by weight
PPM by volume
Lbs/MMCF (gas)
(Other Psychormetric Data Reduction Available. Consult Factory.)
Each Moisture Analyzer incorporates advanced amplification signal conditioning and linearization concepts, and monitors the variation of the electrical capacitance of the sensor as it changes with moisture. The Analyzer uses a set of "curve fitting" algorithms under microprocessor control which adjusts the system to conform to non-linearities (inherent with aluminum oxide sensors) to a high degree or accuracy. Storage of sensor calibration data is accomplished with a plug in EPROM. Three standard models are available. The basic unit provides calculation and display of Multiple Measurement Units, as follows:
Multiple Measurement Units with User Selectable Real Time Calculation:
Provides user selectable units of measurement in Dew Point °C or °F; PPM by Volume, PPM by Weight; lb/MMCF, to be displayed via Front Panel Keyboard input. System pressure and molecular weight of the carrier gass are also input to the hygrometer via the Front panel keyboard and allow for psychrometric data reduction.
Display of average moister reading, rate of change reading, maximum reading, and minimum reading provided.
Other standard features include:
"Display Test" assures that all digital display segments are operable.
Sensor gross failure circuit causes digital display to flash "FAIL."
Microprocessor-based electronics.
MOD 3 Portable Moisture Analyzer

Designed for specific process applications where sampling of high pressure gass and portability are required. It consists of a built-in sampling system, sensor, and the MOD 1 electronics, all housed in a compact, rugged, ABS plastic case designed to withstand field abuse. The MOD 3 was designed for use in crtical applications such as monitoring SF6 gases in circuit breakers and moisture in natural gas transmission systems.
