Care & Maintenance Tips

Always store the pH electrode in 3M KCl storage solution or pH 7.00 buffer when not in use.
Rinse the electrode with distilled water before and after each measurement.
Calibrate the meter regularly — ideally before each use or at least once per week.
Avoid exposing the meter to extreme temperatures or high humidity beyond specified limits.
Replace the electrode when response time slows or calibration becomes difficult.
