  • Manufactured specifically for pH and ORP electrodes
  • Clearly marked expiration date and lot number


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.
