Hygrocontrol Type 83™

Hygrocontrol Type 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.


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


LAR’s hygrometer is suitable for:

  • Maturation, packaging, storage and transportation of food and stimulants
  • Material conditioning in the manufacture of pharmaceutical products
  • Drying processes in the manufacturing and processing ceramic products
  • Process monitoring in process plants in the chemical industry
  • Climate control of clean rooms, paint and incineration plants in the automotive industry, process control of climatic tests and environmental simulation chambers
  • Monitoring of sterilizing equipment in medical
