The DewPro MMY31 measures dew point or ppmv in dry gases. It is a cost-effective, loop-powered dew point transmitter designed for “in-line” installation where a trace moisture measurement is required, but display, alarms, and other features are not needed. The planar capacitive aluminum oxide sensor provides excellent corrosion resistance, longer calibration stability, quick response times, and an exceptionally low temperature coefficient.

The MMY31 mounts directly in-line for applications such as glove boxes, where a bypass is not appropriate. It is easily installed via a 1/2” MNPT or G 1/2 adjustable insertion length compression fitting. Applications include glove boxes, environmental chambers, and high altitude testing.
