COMET H3331 Temperature and humidity regulator with RS232 output


Category: Sensors

Quick Overview:

Product Details

Humidistat, thermostat with two relay outputs. Outdoor, indoor use.

Relative humidity, temperature probe on a cable. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy. Three two-state inputs.

The device is supplied with T+RH probe with 1 meter cable.
