H3431 relative humidity and temperature transmitter with RS485 COMET output

Description

H3431 relative humidity and temperature transmitter with RS485 output with two relay outputs for outdoor and indoor use. The device is equipped with a T+RV probe (sensor) with a 1, 2 or 4 metre cable.

The measured moisture value can be converted to dew-point temperature, absolute humidity, specific humidity, mixing ratio or other formats.
