Clean the liquid junction of your electrodes once a day or at least once a week to prevent clogging and to maintain accuracy. Immerse the electrode in the proper cleaning solution for about 5 minutes.
HANNA® offers a wide range of cleaning solutions, for general purpose and specific applications, to eliminate all kind of dirt or deposit from the electrode, and thus ensure correct measurements.
