Hygrocontrol 85
Relative humidity and temperature meter (hygrometer) for industrial use. The drawn current (4-20mA) responds to measured humidity 0-100% RH.
Principal of Operation
The instrument uses a capacitance type sensing element with polymer dielectric medium. The temperature sensor is a Pt-1000 Ohm RTD. Microprocessor control allows for multipoint calibration. A maximum accuracy of 1.5 %RH is achieved with 8 points. Built in special temperature compensation is to correct humidity values from deviations arising from temperature effects on the sensor and the electronics.
