The LabSen® 841 pH electrode from Apera Instruments is engineered with Swiss sensor technology to ensure high-precision pH measurement in strongly basic solutions (pH 10-14). Featuring an alkali error-resistant glass membrane and a silver ion trap reference system, this electrode is built for accuracy, durability, and reliability in demanding laboratory and industrial applications.

Key Features:

✔ LabSen HA Glass Membrane – Specially designed for strong base solutions, ensuring high accuracy and reproducibility while minimizing alkali error.
✔ Hemispherical Glass Diaphragm – Up to 10 times more robust than standard membranes, providing enhanced impact resistance and durability.
✔ Silver Ion Trap Reference System – Prevents contamination and blockage from silver sulfide, extending the electrode's lifespan.
✔ Long Life Reference System – Ensures stable readings and prolonged usability.
✔ Blue Gel Electrolyte – Non-flowing design prevents air bubbles, improving measurement consistency and ease of use.
✔ Swiss Technology & Materials – Manufactured with proprietary Swiss pH sensor technology for superior performance.
✔ Broad Compatibility – Equipped with a BNC connector, making it compatible with all pH meters that use BNC connectors, including:
???? Apera Instruments PH850, PC850, PH8500, PC8500, PH700, PH910, PC910, PH950, PC950, PH800, PC800, PH820, and PC820.

Compatibility:

???? Temperature Compensation: A separate temperature sensor (e.g., Apera Instruments MP500) is required for automatic temperature compensation, or temperature must be manually entered.
???? Replacement Electrode: Compatible with Apera Instruments PH850-SA and PH8500-SA pH meters.

Warranty:

???? 6-Month Manufacturer's Warranty ensuring long-term reliability and consistent performance.
