Usage and Maintenance
2.1
Connect BNC & RCA plug to the input on the pH meter.
2.2
When measuring, please unscrew the bottle cap, pull out the electrode and rinse it with
deionized water. After using, please put the electrode back into the bottle and screw tight the
cap.
2.3
The electrode must be soaked in 3M KCl solution for storage. Because after long time
exposure in air, Polymer electrolyte will cause shrinkage.
2.4
The electrode’s measuring tip should be soaked in the soaking bottle containing certain amount
of 3M KCl soaking solution to keep the membrane hydrated and junction unblocked. Clean the
Before pulling out or putting back the electrode,
make sure to fully loosen the blue cap on the
storage sleeve so that the electrode can move in
and out smoothly.
