A pH meter. A pH Meter is a device used for potentiometrically measuring the pH, which is either the concentration or the activity of hydrogen ions, of an aqueous solution. It usually has a glass electrode plus a calomel reference electrode, or a combination electrode.
Their concentration determines the current produced by the probe which is measured by the meter. The greater the hydrogen ion concentration, the greater the current produced by the probe. http://www.sensorex.com/support/educatio... A pH meter is used to measure the acidity of a solution. As I'm learning in Chemistry now, H+ ions are responsible for making acids. On a pH meter, 0-6.9 is an acid, 7 is neutral, and 7.1-14 is considered a base. A base, for your extra knowledge, has a high concentration of OH- ions. Anyways, a standard pH meter usually has a probe sticking into the solution hooked up to the machine.
