Ideally a storage solution should be used; never store an electrode in distilled or deionised water. The Hanna Instruments storage solution is specifically formulated to minimise microbial growth and to prevent any diffusion\/osmotic effects from storing a probe in a solution with the highly concentrated inner reference electrolyte. Storing your pH and\/or ORP electrodes in a storage solution will also keep the junction clear.\u003c\/p\u003e \u003cp\u003eMaintaining the hydrated layer and clear junction will help to ensure a fast and reliable measurement. In the case of cleaning your pH electrode in one of our cleaning solutions, we recommend soaking the electrode in the HI-7061-012 GroLine storage solution for at least one hour before taking measurements.\u003c\/p\u003e \u003cp\u003e* Never store pH or ORP electrodes in distilled or deionised water.
