Background and Identification
A pH meter is a scientific instrument capable of measuring the acidity or basicity of a solution. While some simple pH tests involve the chemical reaction of a solution with different substances to give a color signature which can be checked against a reference, modern electrical pH meters monitor the hydrogen-ion activity of a solution as the difference in electrical potential between two electrodes within the solution. This measurement can be extremely useful to healthcare professionals in blood chemistry and analysis.
