The most common cause of pH meter failure is dry storage of the electrode. This causes dehydration of both the glass electrode and wick.
- helps maintain electrode accuracy and response time and eliminates reading 'drift'
- maximises electrode life span by preventing dehydration of the glass electrode and wick
Note: pH buffers 7.0 or 4.0 or distilled water are not suitable for storing pH electrodes. Electrode storage solutions are carefully structured formulations that do not interfere with the chemical composition of the liquid/gel that is contained within the electrode.
