A pH meter is an electronic device used to measure pH which is either the concentration of hydrogen ions in an aqueous solution or the activity of hydrogen ions in an aqueous solution. The pH will indicate whether the solution is acidic or basic, but is not a measure of acidity or alkalinity. pH meters work in liquids, although special probes are sometimes used to measure the pH of semi-solid substances. A pH meter consists of a special measuring probe (a glass electrode) connected to the body that measures and displays the pH reading.
