Thermometer hygrometer with Ethernet interface and relays, humidistat

code: H3530

Humidity, temperature, humidex Ethernet sensor with two relay outputs.


Sensor H3530 is designed for online monitoring of temperature, relative humidity, humidex 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: humidex, dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy.
