Calibration Solution 4 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 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!
