pH & ORP Probe Preparation
Probe Shipping & Storage
pH & ORP probes are shipped in a plastic bottle containing a
solution of pH 4 buffer and potassium chloride. The electrode
should remain in the bottle until it is used.
If the electrode is used infrequently, the bottle and its solution
should be saved and the electrode stored in it. If the solution in
the soaker bottle is missing, fill the bottle with pH 4 buffer.
Take out electrode by loosening plastic top on bottle counter-
clockwise and pulling electrode out. Slide cap and O-ring off
electrode and save.
