LabSen 751 Stainless Steel Sheath Spear pH Electrode
LabSen electrochemical sensors are premium pH electrode with manufacturing technology and key components imported from Switzerland. LabSen751 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
2.1 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 The electrode must be soaked in Protelyte solution for storage. Because
after long time exposure in air, Polymer electrolyte will cause shrinkage.
2.4 The electrode’s measuring tip should be soaked in the soaking bottle
containing certain amount of Protelyte 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.
2.5 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.
2.6 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.
2.7 After 1-year of use, we recommend replacing the electrode to ensure the
best accuracy.
