The AquaSensor is calibrated at the factory but can also be recalculated at the customer’s site. When calibrating the AquaSensor, it has to be brought into contact with a known level of saturation (saturation level standard) and the displayed value compared to the known one. We recommend calibrating the AquaSensor at least once a year.
The available HYDAC AS Calibration and Adjustment Set (stock no. 3122629) is supplied with two saturation levels standards (11.3% and 75.5%).
