Refill And Storage liquid for pH-Meter, 300ml
This liquid is ideal for storage of all pH-probes. The probe should stand in storage solution whenever it is not being used. This will maximise accuracy and prolong the life of the electrode.
You can also fill a little piece of sponge in the caps (watchout, it should not touch the electrode) and keep it constantly wet with storage liquid.
The lifetime of pH-probes depend a lot on the care given to them.
