pH meters are used to measure pH values of drinking water samples, for example pinpointing acidity of rainwater samples. Rain drinking water is is made up of dissolved carbon dioxide that provides a weakly acidic Remedy.
Rinse the pH electrode during the sample beaker following rinsing it with deionized h2o beforehand. To prevent sample contamination, rinse the electrode with deionized water in excess of a waste beaker. The identical beaker useful for sample measurement should really never be utilized to rinse the electrode.
