MAC125 Moisture Analyzer

For
HIGH TEMPERATURE
ABSOLUTE HUMIDITY MEASUREMENT

The MAC125 Moisture Analyzer is a mojor advancement in the measurement of absolute humidity.
The measurement process is solid state. No chemicals, compressed air, wet bulb techniques, optics or mirrors are used. The probe is protected from particles by a 10 micron ceramic filter element, that is cleanable and replacable.
The MAC125 is the latest generation of Absolute Humidity Transmitters from MAC Instruments. The MAC125 and it's predesessors are providing accurate, reliable, high temperature humidity measurement in many difficult applications throughout the world since 1990.
