APERA LabSen 753 Stainless Steel Sheath Spear pH Electrode
INSTALLATION INSTRUCTION
LabSen electrochemical sensors are premium pH electrode with manufacturing technology and key components imported from Switzerland. LabSen753 spear pH electrode adopts spear membrane, which can easily pierce into solid or semi- solid medium. This probe is suitable for pH measuring of cheese, flour products, meat and fruits.
This probe has following features:
- Adopts food grade stainless steel sheath, offers strong protection, comply with food hygiene requirements, suitable for food pH testing.
- Blue gel inner solution, does not flow and will not cause bubble.
- Maintenance-free polymer electrolyte, non-diaphragm structure.
- Long life reference system, has better stability and service life.

Usage and Maintenance
-
Connect BNC & RCA plug to the input on the pH meter.
-
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.
-
The electrode must be soaked in 3M KCl solution for storage. Because after long time exposure in air, Polymer electrolyte will cause shrinkage.
-
The electrode’s measuring tip should be soaked in the soaking bottle containing certain amount of 3M KCl soaking 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.
-
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. -
Spear pH Electrode is suitable for measure wet solid or semi-solid medium. Please forcibly even when piercing, to prevent damage of the electrode. In case the sample medium is too hard (such as meat and fruit); please cut a small hole before piercing the electrode into it.
-
After 1-year of use, we recommend replacing the electrode to ensure the best accuracy.
