products.

This Electrode has following features:

⚫ Adopts food grade stainless steel blade and 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.

2 Usage and Maintenance

2.1 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.

2.2 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.

2.3 Please forcibly even when piercing into meat (especially frozen meat); do not bend it to prevent

damage of the tapered membrane. Wash the electrode and the stainless steel sheath with soapy

water after measurement, the stainless blade can be screwed off and cleaned if necessary.

2.4 The electrode must be soaked in Protelyte solution for storage. Because after long time

exposure in air, Polymer electrolyte will cause shrinkage.

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 The stainless steel sheath and blade have a specially treated coating, it is absolutely forbidden

to damage the coating with sandpaper or blade, otherwise the stainless steel sheath and blade

will get rust in Protelyte solution.

2.7 After 1-year of use, we recommend replacing the electrode to ensure the best accuracy.
