H3331 relative humidity and temperature transmitter with RS232 COMET output

Description

H3331 Relative humidity and temperature transmitter with two relay outputs and RS232 output for indoor and outdoor use.

The device is equipped with a T+RV probe (sensor) with a 1, 2 or 4 metre cable.

The inverter is equipped with two relay outputs for displaying alarms or controlling external devices. It contains three binary inputs for water, smoke, glass break or door contact detection.

The measured humidity value can be converted into a format: dew-point temperature, absolute humidity, specific humidity, mixing ratio or other.
