Technical possibilities of the calibration laboratory - humidity calibration

Measured variable relative humidity

Calibrated hygrometers with rod sensors, hygrometers in which the temperature / humidity measuring point is integrated in the hygrometer, on request.

Calibration item

Calibration range accredited Calibration range (ISO)

Hygrometer, also with transmitter

(10…90) % RH at 22 °C

(5…95) % RH at 22-24 °C

The standard points are 20% RH, 50% RH, 80% RH at 22 ° C for DAkkS calibrations and 25% RH, 50% RH, 75% RH at 22-24 ° C for ISO calibrations.
