A pH meter is a simple device / instrument, popularly used to measure
the acidity and / or the alkalinity of a fluid or substance. The
instrument was invented in by an American chemist Arnold O.Beckman in
the year 1934. It is a kind of a voltmeter that helps to measure the
electrical potential difference between a pH electrode and a reference
electrode. The instrument displays the result in terms of the pH value
of the solution in which they are immersed. A pH meter generally has the following inputs:
- An indicator (ion-sensitive or redox).
- Reference electrodes.
- Temperature sensors including thermoresistors or thermocouples.
These instruments are engineered for fast, convenient electrode potential and also for providing accurate measurements and analysis. A pH meter is connected to the pH electrode, and put in such a way that it displays the ready pH value.
