Relative Humidity Measurement Hygrometers

Our HYGROCONTROL™ Type 85 Relative Humidity Hygrometer 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.

  • 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.
  • Readings of humidity and temperature is also via CAN-BUS available (Type 84).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 an easy re-calibration. 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.


The HYGROCONTROL Type 85 Relative Humidity Hygrometer is a high-precision instrument designed to measure and monitor relative humidity and temperature levels in various environments. Some benefits of this hygrometer include:

  • High accuracy: Has a range of ±1% accuracy in relative humidity measurements and ±0.1°C in temperature measurements. This ensures that the humidity and temperature levels are within the desired range, making it suitable for use in critical applications such as pharmaceutical manufacturing and research laboratories.
  • Versatile: Available in different models and options to suit various needs and requirements. For example, it can come with an integrated sensor or a remote probe, making it suitable for use in a wide range of applications, including industrial, commercial, and residential settings.
