Electrodes that are frequently used can be placed (stored) in distilled water. 98 + 88 88 * Cleaning of conductivity electrodes: Organic stains on the electrode can be cleaned with warm water containing detergent, or with alcohol. Calcium and magnesium precipitates are best cleaned with 10% citric acid. The electrode plate or pole can only be cleaned by chemical methods or by shaking in water. Wiping the electrode plate will damage the coating (platinum black) on the electrode surface. 100 + 89 89 * The equipment should be calibrated before each use. It is recommended to calibrate it every 3 months for long-term use.
