Hygrocontrol Type 83 hygrometer
The Hygrocontrol Type 83 Hygrometer was constructed for critical relative humidity and stainless steel are available in different lengths and diameters. Analog current calibration over RS 232 3V. There are several different sensor filters available.
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.
