H7531 Thermo-Hygrometer Barometer with Ethernet Interface and Relay

H7531
Ambient temperature, relative humidity, atmospheric pressure sensor with two relay outputs. Humidity index reading.
The H7531 sensor is designed for in-line monitoring of temperature and relative humidity in non-aggressive air. Three binary inputs are used to detect bistatic signals, which is an advantage. Other equipment can be controlled via two relay outputs.
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 device comes with a T+RH (humidity and temperature) probe with a 1 meter cable. Optional cable lengths of 2 or 4 meters are also available.
Warranty: 3 years
