H3331 | Humidistat, Thermostat, 3 x State Inputs

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.

INCLUDED IN DELIVERY:

• H3331
• Instruction Manual
• Traceable Calibration Certificate
• FREE software TSensor for Configuring of the Transmitter

3 year warranty
