pH meters need some care and attention. A little effort will keep them in good shape, which will enhance and ensure their accuracy and extend their useful life.
This solution can be used to store pH meters when not in use. Basically the probe – glass bulb – at the end of the meter should be just immersed in the solution. This will condition the probe and maximise its useful life. The same solution can be used for refilling the probes on certain meters.
Contains 3 molar KCl
