Dennerle pH 7 Calibration Solution 50 ml Calibration Solution 7 for pH Eletrodes, Content: 50 ml
The accuracy of the calibration depends to a decisive extent on the quality of the employed calibrating solutions. Always use fresh calibrating solutions and calibrate the electrodes in separate, clean receptacles, ideally in the Dennerle pH 7 Calibration Solution 50 ml calibrating station (accessorie). Discard used calibrating solutions. Do not carry out calibration in the supply bottles - water on the pH-electrode may alter the calibrating solutions!
