HI70300-023 is a GroLine storage solution prepared with reagent grade chemicals that can be used to ensure optimum performance of your pH and ORP electrodes.
The Hanna Instruments storage solution is specifically formulated to minimize microbial growth and 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 keeps the junction clear, maintains the hydrated layer of the electrode, and clears the junction to ensure a fast and reliable measurement.
