APERA LabSen 821 Food pH Electrode
LabSen 821 Food pH Electrode
LabSen electrochemical sensors are premium pH electrode with manufacturing
technology and key components imported from Switzerland. LabSen 821 food pH
electrode is suitable for protein-containing dairy and food.
This probe has following features:
- Impact-resist membrane (see the right picture)there is no danger of electrode breakage during normal use.
- Protelyte reference solution does not react with protein; 3 ceramic pores reduce the possibility that junction being blocked.
- Blue gel inner solution, does not flow and will not cause bubble.
- Long life reference system, and silver ion trap reference prevent the contamination of the junction when testing sample contains sulfides and proteins, which helps to improve the stability and service life of the electrode.

Usage and Maintenance
-
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.
-
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.
-
After a period of usage, the reference solution will be running 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. 2.4 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.
-
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. 2.6 After 1-year of use, we recommend replacing the electrode to ensure the best accuracy.
Warranty
We warrant this electrode free from defects in material and workmanship and
