The GE General Eastern DewPro MMR30 is a compact, mid-range moisture transmitter designed specifically for refrigeration dryer manufacturers and users. The DewPro MMR30 measures dew point at line pressure or atmospheric pressure and installs easily on a dryer outlet header.

The DewPro MMR30 uses a proven polymer capacitive sensor to provide a measurement range of 5°F to 185°F (-15°C to 85°C) with ±1.8°F (±1.0°C) accuracy. The optional integrated display with user interface provides full programming and diagnostic capability.
