The LabSen® 851-1 pH electrode from Apera Instruments is manufactured using proprietary Swiss sensor technology and materials. It is specially designed for precise measurement of viscous samples such as cosmetics, lacquers, paints, etc.

LabSen conical glass membrane - the membrane provides a large surface area, which enables a fast response, and is 10 times more robust than conventional glass membranes, protecting the electrode from accidental damage.

Silver Ion Trap Reference System + Protelyte Electrolyte - The LabSen 851-1 pH electrode features a silver ion trap reference system and a protelyte reference solution, minimizing the risk of clogging the junction.

• Proprietary pH sensor technology and materials from Switzerland
• The LabSen conical glass membrane is ideal for viscous samples.
• The combination of silver ion trap reference system & Protelyte electrolyte minimizes the risk of clogging the junction.
• Blue gel electrolyte, does not flow and does not cause air bubbles

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.
