Pool Line Electrode Storage Solution (25 x 20 mL) - HI7003004P


In stock

HI7003004P Pool Line Electrode Storage solution is prepared with reagent grade chemicals that can be used to ensure optimum performance of pH and ORP meters. Properly storing your pH electrode in a solution keeps the glass membrane properly hydrated along with the junction that is part of the measurement system. A free-flowing junction allows for fast and stable measurements.

  • Designed for storing any pH or ORP electrode to maintain optimum performance
  • 25 sachets of buffer with 20 mL of solution
  • 5 year shelf life for unopened sachets


HI7003004P Pool Line Electrode Storage Solution is a specially formulated storage solution for the proper maintenance of pH and ORP probes when not in use. To optimize the response time it is important to keep the pH bulb hydrated. It is also important to keep the junction of both pH and ORP probes. All electrodes have a junction that is an electrical pathway between the solution tested and an inner electrode. Keeping this junction hydrated keeps the junction free flowing, which provides for faster and more stable readings.

For process probes the HI7003004P should also be used to rehydrate the electrode after cleaning the oils and lotions that will coat the sensors over time. After using a cleaning solution the probe should be allowed to soak for 15 minutes to allow for the hydration layer to form. After that time then the a calibration should be performed.

A well-maintained swimming pool, hot tub, or spa starts with accurate readings and the proper storage of a pH/ORP electrode is required to ensure maximum performance and long life.
