pH Meters and ORP Meters
pH meters and ORP meters are used to measure or monitor potential of hydrogen (pH) and oxidation-reduction potential (ORP). pH is the negative logarithm of the hydrogen ion activity in solution. The pH value of a substance is directly related to the ratio of the hydrogen ion [H+] and the hydroxyl
