This instrument is a laboratory pH/ORP analyzer commonly used to measure the acidity and alkalinity of aqueous solutions. The core of a benchtop pH meter is a glass electrode and a reference electrode. When the thin glass electrode membrane comes into contact with a solution, it produces a potential change proportional to the hydrogen ion concentration in the solution. This change is directly proportional to the pH value of the solution. The reference electrode provides a stable potential baseline, which is used to correct for potential drift during the glass electrode measurement process. The instrument measures the potential difference between the glass electrode and the reference electrode and converts it into a corresponding pH value for display.
