The M Series Aluminum Oxide Moisture Probes, are used in conjunction with the Panametrics hygrometer connected by cable. The film thickness for the M series probe is critical to achieve quick results with excellent calibration stability. The use of an oxide film thickness can improve performance considerably exhibiting true absolute humidity, rather than relative humidity response. Operating temperature range is -166F to 158F (-110C to 70C) with a pressure range from 5000 psig (345 bar).
Advancements in moisture calibrations now allow probes to use flow, temperature and pressure measurements, traceable to NIST/NPL, to record accurate moisture concentrations. Measurement of water vapor pressure is easily achieved in both gases and liquids using the M Series probe. Cable length between the hygrometer and probe can be upto 2000ft. This allows the M series to avoid limitations providing easy installation and little to no maintenance,
