Our HYGROCONTROL™ Type 81/82 Relative Humidity 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.
