Storage of controller probes

[krisfal]

I was told that the ORP and PH probes should be kept wet. How do you keep them wet if you are going to be storing them for a length of time?

Thanks in advance for your advice.

The PH probe warranties elude to that, but when you buy them new, most of the time the rubber end caps are dry and full of crystals. I called the suppler and verified with the manufacturer that as long as the new ones are kept protected and the used ones are not allowed to fully dry for a prolonged period that all is OK.

To keep wet, seal end in a plastic bag with rubber bands. The calibration fluid works well. Can also use a finger from a rubber glove

I dont know about the ORP but the PH should be stored in potassium chloride
