A pH meter measures a pH or the acidity/alkalinity of substances. Most pH meters rely on a glass electrode that measures the number of hydrogen ions in the solution. Usually, pH meters need to be ...

pH meters are electric appliances used for measuring the- alkalinity or acidity of a solution. pH is measured using potentiometric methods or pH indicators such as indicator solutions or strips ...

pH is a measurable parameter between the values of 0 and 14, defining the acidity or alkalinity of a solution. Solutions with a pH = 7 are considered neutral, pH < 7 are considered acidic and pH > 7 ...
