VP Dew Point Sensor

Encountering humidity in your pipes is acceptable to a certain level, but you don’t want to exceed the acceptable limits. In order to stay in control of your humidity by managing your temperature and pressure levels you need dew point transmitters.

The VP Dew Point Sensor is the smart dew point transmitter with a large measurement range of -70..+60 ⁰C, so you can measure downstream a refrigerant type dryers as well as a desiccant-type dryer. The sensor has multiple outputs, alarm LED, and built-in autocalibration.
