The LabSen® 851-S pH electrode from Apera Instruments is manufactured using proprietary Swiss sensor technology and materials. It is specially designed for precise measurement of high viscosity samples such as cosmetics, coatings, syrups, resins, adhesives, etc.
LabSen S-type hemispherical glass diaphragm – The low-resistance and rugged glass diaphragm provides a fast response so readings stabilize quickly, and is up to 10 times more robust against shock or accidental contact than conventional products.
Pre-pressurized reference system – The pre-pressurized reference system allows the electrolyte to flow through the junction even with highly viscous samples. This enables the electrode to reliably measure even samples with high viscosity.
- Patented pH sensor technology and materials from Switzerland
- Unique LabSen hemispherical glass membrane, which has a faster response rate, better repeatability and robustness.
- Pre-pressurized reference system for smooth electrolyte flow
- Silver ion trap reference system prevents contamination of the electrode and increases its service life
The electrode uses a BNC connector that is compatible with all pH meters that use BNC connectors, such as Apera Instruments PH850, PC850, PH8500, PC8500, PH700, PH910, PC910, PH950, PC950,PH800, PH800, PC800, PH820 and PC820. A temperature sensor is not integrated. For automatic temperature compensation, a separate temperature sensor (e.g. Apera Instruments MP500) is required, or the temperature must be entered manually.
This electrode has a 6-month manufacturer’s warranty.
