APERA LabSen 881 Low Temperature pH Electrode
LabSen 881 Low Temperature pH Electrode
LabSen electrochemical sensors are WF premium pH electrode with manufacturing technology and key components imported from Switzerland. LabSen881 pH electrode is suitable for low temperature samples.
This probe has following features:-
- Electrode structure suitable for low temperature: conical low resistance membrane and Proselyte reference solution.
- Impact-resist membrane (see the right picture), there is no danger of electrode breakage during normal use.
- Blue gel inner solution, does not flow and will not cause bubble.
- Silver ion trap reference prevents the contamination of the junction when testing sample contains sulfides and proteins.
Technical Data
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. 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.
-
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 running low. Whenever the level falls to 1/2
height of the electrode, add Protelyte solution to the refilling hole by using syringe or pipette. -
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 sinker in pure water or buffer solution for long.
-
After 1-year of use, we recommend replacing the electrode to ensure the best accuracy.
