Replacement cap for Bluelab pH and Soil pH Probes

It is essential that the storage cap is placed back on the probe tip of the pH probe after use and when being stored. "If it dries it dies!"

Keep the pH probe tip wet by ensuring there is enough Bluelab pH Probe KCl Storage Solution to cover the probe
