Usage and Maintenance
2.1
Testing surface need to be clean and wet, such as wet the surface of skin or textile by distilled
water.
2.2
Connect BNC plug to the input on the pH meter.
2.3
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.
2.4
The electrode’s 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
The connector of the electrode should keep 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.
2.6
After 1-year of use, we recommend replacing the electrode to ensure the best accuracy.
