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.
Use a calibrated pH meter, or paper pH test strips, to measure pH. ï· The pH meter must be calibrated using a 2-point calibration with pH 4.0 and 7.0 buffers. The pH meter must be calibrated each day that you use it. monitor the pH of foods with an equilibrium pH greater than 4.0.
