Hanna Storage solution, 500ml
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 a n 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.
* Never store pH or ORP electrodes in distilled or deionized water. Doing so will shorten the life of the sensor.
