CLEANING AND MAINTENANCE SOLUTIONS - Всичко за вашите растения!
Immerse the electrode in a 3.8 to 4.0 molar solution of KCL (sodium chloride) heated to 50°C for 1 hour. Cool the KCL solution to room temperature and rinse the electrode with distilled water. This procedure will rid the reference electrode of contaminants.
You have to be careful with the electrodes. Each electrode must be completely cleaned and calibrated to the specified value before measurement. Handling, storage and maintenance have a significant effect on the accuracy and lifetime of the pH electrode. Even small phenomena such as air bubbles, crystallization, low electrolyte level, KCl electrolyte underflow or electrode contamination can cause problems.
