LabSen 851-1 Viscous pH Electrode Electrochemical Sensors
Product Information:
The LabSen 851-1 Viscous pH Electrode is a premium pH electrode
with manufacturing technology and key components imported from
Switzerland. It is specifically designed for use with cosmetics and
viscous samples. The electrode features an impact-resistant
membrane to prevent breakage during normal use. It also has a
conical low resistance membrane, Protelyte reference solution, and
a junction of 3 ceramic cores, making it suitable for measuring
viscous samples. The electrode’s blue gel inner solution does not
flow and avoids bubble formation. Additionally, the silver ion trap
reference prevents contamination of the junction when testing
samples containing sulfides and proteins.

- Temperature Range: Not specified
- Shaft Material: Not specified
- Membrane Shape: Conical
- Reference Junction: Silver Ion Trap, Ceramic x 3
- Electrolyte Soaking Solution: Not specified
- Electrode Dimension: Not specified
- Connector Cable: Not specified
Product Usage Instructions:
- Before measuring, unscrew the bottle cap, pull out the
electrode, and rinse it with deionized water. - After use, put the electrode back into the bottle and screw the
cap tightly. - Prior to measurement, remove the rubber plug to maintain
pressure of the reference solution and ensure a consistent flow
rate and stable potentials of the junction. - When the reference solution level falls below half the height
of the electrode, add Protelyte solution to the refilling hole
using a syringe or pipette. - Keep the electrode connector clean and dry. If it gets
contaminated, clean it with medical cotton and absolute alcohol,
then blow dry to prevent short circuits and slow reactions. - Soak the measuring tip of the electrode in a soaking bottle
containing Protelyte solution to keep the membrane hydrated and
junction unblocked. Replace the storage solution if it becomes
turbid and mildewed. Do not store the electrode in pure water or
buffer solution for long periods. - After 1 year of use, it is recommended to replace the electrode
for optimal accuracy.

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 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.
2.3 After a period of usage, the reference solution will running low. Whenever the level falls below 1/2 height of the electrode, add Protelyte solution to the refilling hole by using a syringe or pipette.
2.4 The connector of the electrode should be 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.
2.5 The electrode’s measuring tip should be soaked in the soaking bottle containing Protelyte 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 stored 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.
3 Warranty We warrant this electrode free from defects in material and workmanship and agrees to repair or replace free of charge, at option of APERA INSTRUMENTS any malfunctioned or damaged product attributable to responsibility of APERA INSTRUMENTS for a period of six months. Warranty period is the time limit to provide free service for the products purchased by customers, not the service life of the tester or electrodes.
This limited warranty does not cover any damages due to: transportation; storage; improper use; failure to follow the product instructions or to perform any preventive maintenance; modifications; combination or use with any products, materials, processes, systems or other matter not provided or authorized in writing by us; unauthorized repair; normal wear and tear; or external causes such as accidents, abuse, or other actions or events beyond our reasonable control.
