Explanation: A pH meter is a device used to measure the acidity or alkalinity of a solution. It works by measuring the electrical potential difference between a pH electrode and a reference electrode, which is proportional to the pH of the solution. pH meters are commonly used in laboratory and process applications to monitor the pH of solutions in industries such as food and beverage, pharmaceuticals, and wastewater treatment.
