H3531P Compressed Air Thermometer Hygrometer with Ethernet Interface and Relay

H3531P
Compressed air ambient humidity, temperature Ethernet sensor with two relay outputs.T+RH probe made of hard anodized hard aluminum for compressed air up to 25 bars, with cable. Humidity readings.
The H3531P sensor is used for in-line monitoring of the temperature and relative humidity of non-corrosive air. The advantage is that there are three binary inputs for detecting bi-state signals. Other equipment is controlled by two relay outputs.
Highly accurate capacitive polymer sensors ensure excellent long-term calibration stability and final 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 T+RH probe with a 1 meter long cable. The cable length is available in 2 or 4 meters.
