2 Usage and Maintenance

2.1 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.
2.2 Polymer reference electrode is a kind of high quality reference electrode with the feature of nondiaphragm, hard to be contaminated, compression resistance and resistance to organic solution. It is almost suitable for all pH measurement solution such as solution containing fat, oils, sulfide and protein, effluent, weak ion solution, emulsion and suspension.
2.3 The connector of the electrode should be kept clean and dry. If being contaminated, please clean it with medical cotton and absolute alcohol and blow dry to prevent the short circuit of the
electrode and slow reaction of electrode.
2.4 The electrode measuring tip should be soaked in the soaking bottle containing certain amount of storage solution to keep the membrane hydrated and junction unblocked. Clean the bottle and replace the storage solution if the storage solution gets turbid and mildewed. The electrode should never be sinked in pure water or buffer solution for long.
2.5 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.
2.6 After 1-year of use, we recommend replacing the electrode to ensure the best accuracy.
