pH Electrode Storage Solution (500 mL)

HI70300L is a specially formulated electrode storage solution that can be used to store your pH electrode*. To ensure the best response time, the sensor tip and the reference junction of the pH electrode should be kept moist when not in use. Placing the pH electrode in a small glass filled with storage solution or replacing the solution in the protective cap is an easy way to store the electrode. The HI70300L should also be used to rehydrate the electrode after cleaning by soaking for at least one hour before taking measurements.
