The Panametrics DewPro MMY31 is a cost-effective, loop-powered dew point transmitter probe engineered for straightforward "in-line" installation in applications where a display or additional features are not required . It is particularly well-suited for spaces like glove boxes where a bypass loop is impractical, as well as for use behind desiccant dryers, in environmental chambers, and for process air control.

At its core is a fast-response planar capacitive aluminum oxide sensor, which provides excellent corrosion resistance, extended calibration stability, and an exceptionally low temperature coefficient . The probe installs easily via a 1/2" MNPT or G 1/2" compression fitting, featuring an adjustable insertion length to optimize its position within the gas stream. The simple 4-20 mA loop-powered electrical connection and robust industrial design with an IP65 enclosure make it a reliable and easy-to-integrate solution for trace moisture measurement.
