code: H7531
Ambient temperature, relative humidity, atmospheric pressure with two relay outputs. Humidex reading.
Sensor H7531 is designed for online monitoring of temperature, relative humidity of air without aggressive substances. Three binary inputs to detection of two-states signals are the advantage. Other devices are controlled by two relay outputs.
High precision capacitive polymer sensor ensures excellent long term calibration stability and ultimate accuracy. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy.
The device is supplied with T+RH probe with 1m cable. Cable lengths 2m or 4m available optionally.
