reaction of electrode.
e) The electrode’s measuring tip should be soaked in the storage bottle containing 3M KCL storage
solution to keep the membrane hydrated and junction unblocked. When measuring, please unscrew
the bottle cap, pull out the electrode and rinse it with deionized or distilled water. After using, please
put the electrode back into the bottle and screw tight the cap. Clean the bottle and replace the storage
solution if the storage solution gets turbid or mildewed. The electrode should never be soaked in
purified water or buffer solution for long.
f)
NOTE: All the tests should be sample tests, meaning after measurement, the samples should be
abandoned and not be used for its original purpose again.
g) After 1-year of use, we recommend replacing the aged electrode to achieve the best accuracy.
