Our Type 81/82 is a wall-mounted, high-precision relative humidity and temperature hygrometer ideal for industrial use. Minimal drift, easy mounting, easy to configure, and install. The Type 81/82 delivers excellent stability even with temperature fluctuations. A variety of probes available to satisfy many applications.
High-precision relative humidity and temperature meter (hygrometer) for industrial use. The following humidity units can be calculated, displayed and issued. 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.
