H3531R

H3531R Rack Mount Thermometer Hygrometer with Ethernet Interface and Relay

Humidity and temperature monitor with two relay outputs. Support humidity index calculation.

The H3531R sensor is designed for in-line monitoring of air temperature and relative humidity of non-aggressive materials. Three binary inputs are used to detect two status signals, which is one of its advantages. Two relay outputs can be used to control other equipment.

Highly accurate capacitive polymer sensors ensure excellent long-term calibration stability and ultimate accuracy. Measurements can also be converted to other humidity interpretations: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific heat.

The unit comes with a 1 meter T+RH probe cable with the option of a 2 meter or 4 meter cable length.

Measurement data can be processed and analyzed in the following ways:

Online Processing on COMET Cloud
Processing with COMET Database Software
Integrating data into third-party systems

Warranty: 3 years
