Hygrocontrol 83

Closed loop relative humidity and temperature meter (hygrometer) for industrial use. The drawn current (4-20mA) responds to measured humidity 0-100% RH.

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.



  1. Moisture meters with the highest accuracy for measuring relative humidity and temperature in enclosures with protection class IP 65 with fixed or flexible probes.
  2. Various probe tubes (from PP to stainless steel) are available, including pressure-proof for operation pressure + vacuum.
  3. Measured values can be displayed as relative or absolute values.
  4. Microprocessor-controlled measurement and calibration.
  5. Linear measurements outputs for all possible dimensions of humidity and temperature.
  6. Readings of humidity and temperature is also via CAN-BUS available (Type 84).
