H3331 Temperature and humidity regulator with RS232 output

H3331

Humidity controller, thermostat with two relay outputs. Can be used both indoors and outdoors.

Relative humidity and temperature probes with cables. Temperature probe. Measurements can also be converted to other humidity interpretations: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific heat. Three binary inputs are available.

The device comes with a T+RH (humidity and temperature) probe with a 1 meter cable.

Warranty: 3 years
