Frequently asked questions

The manual recommends calibrating at least once a week, or after testing aggressive chemicals, or if the display shows "CAL DUE". You should also calibrate when the pH electrode is replaced or when high accuracy is required.

The manual mentions using pH 4.01 and pH 7.01 buffer solutions. For more accurate readings at pH 3.5, it suggests using an additional pH 1.68 buffer solution.

After measuring, ensure to rinse the electrode with distilled water and store it with the cap containing a storage solution (HI70300L or pH 4.01 buffer). Once a week, you should soak the electrode in cleaning solution (HI7061L) for two minutes, rinse it with distilled water, and then store it in the cap.
