The Panametrics DewPro MMY31, formerly General Eastern, dew point transmitter probe measures dew point or ppmv in dry gases. The DewPro MMY31 dew point probe 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 Panametrics DewPro MMY31 dew point transmitter probe features a planar capacitive aluminum oxide sensor, which provides excellent corrosion resistance, longer calibration stability, quick responses times, and an exceptionally low temperature coefficient.

The DewPro MMY31 dew point transmitter probe from Panametrics mounts directly in-line for applications such as glove boxes, where a bypass is not appropriate but can also be used behind a desiccant dryer. The DewPro MMY31 is easily installed via a 1/2" MNPT or G 1/2" compression fitting with an adjustable insertion length.

Applications for the Panametrics DewPro MMY31 Dew Point Transmitter Probe

  • Glove boxes
  • Environmental chambers
  • Process air control
  • In-line process measurements
