2.1
When measuring, please unscrew the bottle cap, pull out the electrode and rinse it with
2.2
deionized water. After using, please put the electrode back into the bottle and screw tight the
cap.
The electrode must be soaked in 3M KCl solution for storage. Because after long time
2.3
exposure in air, Polymer electrolyte will cause shrinkage.
The electrode's measuring tip should be soaked in the soaking bottle containing certain
2.4
amount of 3M KCl soaking solution to keep the membrane hydrated and junction unblocked.
