LabSen 821 Food pH Electrode

User Manual

LabSen electrochemical sensors are premium pH electrodes with manufacturing technology

and key components imported from Switzerland. LabSen 821 food pH electrode is ideal for

protein-containing dairy products, beverages, and liquid food.

This probe has following features:

l Impact-resistant membrane (see the right picture)，there is no danger of

electrode breakage during normal use.

l Protelyte reference solution does not react with protein; 3 ceramic pores

reduce the possibility that the junction could be blocked.

l Blue gel inner solution, does not flow and will not cause a bubble.

l Long life reference system, and silver ion trap reference prevent the

contamination of the junction when testing samples containing sulfides and

proteins, which helps to improve the stability and service life of the electrode.

2. Usage and Maintenance

2.1 Prior to measurement, remove the rubber plug to maintain pressure of the reference solution,

keep consistent flow rate of reference solution and stable potentials of junction.

2.2 After a period of usage, the reference solution will run low. Whenever the level falls to 1/2

height of the electrode, add 3M KCL solution to the refilling hole by using syringe or pipette.

2.3 The connector of the electrode should keep clean and dry. If 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’s measuring tip should be soaked in the soaking bottle containing storage

solution to keep the membrane hydrated and junction unblocked. 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. Clean the bottle and

replace the storage solution if the storage solution gets turbid and mildewed. The electrode

should never be soaked in purified water or buffer solution for long.

2.5 After 1-year of use, we recommend replacing the electrode for best accuracy.
