The system can be used to calibrate electronic thermo hygrometers, hair hygrometers, thermographs, hygrographs and psychrometers. A climatic chamber creates a homogenous temperature and humidity field. Within this field, instruments are compared to a reference thermo hygrometer. A dew point mirror is used as a reference.

We automate the calibration process where possible. The software controls the chamber temperature and relative humidity and takes readings from the reference thermo hygrometer. Electronic thermo hygrometers can be calibrated automatically. Multiple instruments connect to a multimeter via channel switch – Matrix. The system can handle up to 45 instruments at a time. The actual maximum number of instruments depends on their size and the size of the chamber.
