Immerse the electrode in HI70300 storage solution for 2 hours to activate it.
Use pH 7.01 (HI7007) first, then use pH 4.01 (HI7004) for acidic samples or pH 10.0 (HI7010) for alkaline samples.
Large differences could be due to a lack of calibration or a dry electrode.
No, you must never use distilled or deionized water for storage purposes.
