Ambient temperature, relative humidity, atmospheric pressure with two relay outputs. Humidex reading.
The H7531 sensor is designed for online monitoring of temperature, relative humidity of the air without aggressive substances.
Three binary inputs for detection of two-state signals are the advantage.
The other devices are controlled by two relay outputs.
The high precision capacitive polymer sensor provides excellent long term calibration stability and ultimate precision.
The measured values are also converted to other interpretations of humidity: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy.
The device is supplied with a T + RH probe with a 1 m cable. Cable lengths 2 m or 4 m available as an option.
Power supply is not included.
