LabSen 232 Premium pH Electrode
User Manual
LabSen electrochemical sensors are premium pH electrode with manufacturing technology and key
components imported from Switzerland. LabSen 232 premium pH electrode adopts polymer as solid
electrolyte, non-diaphragm electrode structure. It is suitable for the pH measurement of emulsion,
suspension, effluent, samples containing protein and sulfide.
This probe has following features:
⚫
Impact-resist membrane (see the right picture), there is no danger of
electrode breakage during normal use.
⚫
Maintenance-free polymer electrolyte, non-diaphragm structure.
⚫
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
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
Polymer reference electrode is a kind of high quality reference electrode with the feature of non-
diaphragm, 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.
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.
