Usage and Maintenance

2.1 Connect electrode to S7-BNC cable, and then connect BNC 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 After long time exposure in air, Polymer electrolyte will cause shrinkage. It will not happen in
measurement status. The electrode must be soaked in 3M KCl solution for storage. After long
time soaking, there will be some floccules dissolving out from 3M KCl solution, this is normal
phenomenon.
