pH meter is used to measure pH of water ranging in between 0 to 14 pH. It is incorporated organic probe to detect the Hydrogen ion concentration in the solution. The pH meter consumes power of 220230 Volts, 5060 Hz AC. It measures the acidity and alkalinity of the solution. The equipment works on the principle of measuring potential difference between pH electrode and a reference electrode. It is an electronic device offers immense application in laboratory works to find out the nature of the solution used in labs.
