WebbPerforming pH meter calibration. Start by rinsing the electrode in DI water. Either use a rinse bottle, or fill a beaker with your DI water and stir the electrode gently for 4-6 seconds. Hanna Tip: Hanna recommends rinsing with pure water, such as deionized (DI), distilled, RO, or demineralized (demi) water.
