3. Use, maintenance and precautions

1. The saturated potassium chloride solution in the electrode tube must reach a precise level. (The silver chloride coating must be immersed in this solution.)

2. When measuring with the electrode, the test area (including the junction between the platinum core and the sand) must be immersed simultaneously.

3. The standard electrode solution is a saturated quinone-hydroquinone solution with a shelf life of 48 hours. (Appendix: Preparation of a saturated quinone-hydroquinone solution: add excess quinone-hydroquinone to a pH 4.00 buffer solution until saturation.) Standard ORP potential of 320 mV. 4. If the platinum electrode wire is soiled with grease, clean it gently with a cotton ball soaked in acetone or alcohol. For insoluble inorganic contaminants, rub the area with 1 mol/L hydrochloric acid. The electrode can be used daily. Clean the electrodes with clean toilet paper.
