Replacement pH Sensor, user-replaceable, features a unique/porous liquid-junction.
Note: The pH sensor in the Myron L pDS must be maintained with an electrode strorage solution whenever it is in storage or not being used. An electrode storage solution will keep your probe hydrated and protect the electrolyte embeded inside the probe. If the probe becomes de-hydrated it will most like fail and need to be replaced by the RPG replacement probe.
Electrode Storage Solution can be purchased seperately in our store by following this link.
