A pH meter/controller is an instrument used to test and monitor the pH value of a solution. It works by the principle of primary battery, of which the electromotive force between two electrodes is based on the Nernst Law. Electromotive force of primary battery is affected by both property of electrodes and hydrogen ion concentration in the solution. There is a correspondence relationship between the electromotive force and hydrogen ion concentration of the primary battery, namely negative logarithm of the hydrogen ion concentration is equal to the pH value.
PH meter is an ordinary analytic instrument and is widely used in agriculture, environmental protection, industry and other fields. PH meters can be categorized as pen type pH meter, benchtop pH meter, handheld pH meter, laboratory pH meter and industrial online pH meter.
