Explore our high-precision relative humidity and temperature meter (hygrometers) for industrial use.  Our Hygrocontrol Hygrometers measure the amount of moisture or humidity in the air, or any confined spaces. They can measure absolute, relative, or dew point temperature.

High-precision relative humidity Type 81, 82 for industrial use can be calculated, displayed and issued to measure dew point [°C, °F], absolute humidity [g/scm], specific humidity [g/kg] and enthalpy [kJ/kg]. The temperature can be displayed as °C or °F.

PRINCIPLE OF OPERATION

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.
