A pH meter is an essential scientific instrument used to measure the acidity or alkalinity of a solution by determining its pH level. It comprises a probe with a glass electrode sensitive to hydrogen ions and a reference electrode for stable voltage comparison, connected to an electronic meter that displays the pH reading. These meters are widely used in laboratories, industry, environmental monitoring, and education for applications ranging from water quality testing to food production.
