Hanna Instruments storage solution is specifically formulated to minimize microbial growth and to prevent any spillover effects. Storing your pH and / or ORP electrodes in a storage solution will also keep the junction clear. Keeping the layer hydrated and the junction clear will help ensure a quick and reliable measurement.

To ensure optimal response time, the glass sensor tip and electrode reference junction should be kept wet and not dry out when not in use. HI70300S solution can also be used to rehydrate the electrode after a cleaning procedure by soaking it for at least one hour before taking measurements.

The HI70300S solution was manufactured specifically for pH and ORP / Redox electrodes

25mL airtight bottle with a tamper-evident seal, ensures the quality and freshness of the solution.
