ELECTRODE MAINTENANCE & INSTALLATION AND FIXED
PH electrode is not used at ordinary times and can be soaked in 3mol/l KCL solution or saturated KCL solution. It is strictly prohibited to immerse the electrode in distilled water and deionize the water or tap water with minimal plasma content.If the PH electrode is contaminated with inorganic substances, it can be cleaned with 0.1mol/l Hcl or NaOH solution for a few minutes and then washed with distilled water. If the PH electrode is contaminated with organic substances, it can be cleaned with alcohol or acetone and then cleaned with distilled water.(note: the protective cap before the electrode should be removed when using);
Clean the electrode with tap water every 3 months or 6 months according to the working environment.
