LabSen 371 Plastic Flat pH Electrode
LabSen electrochemical sensors are premium pH electrode with manufacturing
technology and key components imported from Switzerland. LabSen 371 plastic
flat pH electrode adopts flat membrane and PTFE junction structure. It is
suitable for wet solid and semi-solid surface, such as paper, skin, textile
and leather.
This probe has following features:
- Anti-corrosion POM (Polyoxymethylene) shaft, have good mechanical performance.
- Blue gel inner solution, does not flow and will not cause bubble.
- Long life reference system, has better stability and service life.

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.
