(0 mV at pH 7, based on 25°C working temperature). Ho- wever, because most pH electrodes do not exactly replicate the ideal electrode and because the working temperature may differ from 25°C, it is necessary to calibrate the instrument to ensure measurement accuracy of the combined pH electrode.

At the same time the display will show a Data Hold indicator. To release the display freeze function, press the Data. Hold Button again; the Data Hold indicator will disappear from the display. v) After taking a measurement, rinse the electrode in distilled water. AL10pH...
Electrodes are subjected to a natural ageing effect, which in- duces shift of the offset point and gradient of the electrode. For slowing down the ageing effect and for maintaining the performance and accuracy, please note the following considerations: AL10pH...
