The Hygrocontrol Type 85 RH and Temperature Transmitter 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.

The Type 85 was constructed for critical relative humidity and temperature measurements in cases without hazardous conditions. The exchangeable probes with built-in memory of the calibration can be replaced in seconds and allow minimal maintenance. Housing made of PC and probe tubes made of PP, PTFE and stainless steel are available in different lengths and diameters. Analog current and voltage outputs are selectable. The graphic display and accessories allow for a easy re-calibration. There are several different sensor filter available.
