The LabSen® 831 pH electrode from Apera Instruments is engineered with Swiss sensor technology to ensure precise pH measurement in strongly acidic solutions, including hydrofluoric acid (HF) solutions (≥3 pH, 1g/L HF tolerance). With a hydrofluoric acid-resistant glass diaphragm and silver ion trap reference system, this electrode offers durability, accuracy, and reliability for laboratory and industrial applications.

Key Features:

✔ LabSen HF Glass Diaphragm – Specially designed for strong acids and hydrofluoric acid (HF) solutions (≥3 pH), offering fast, precise, and reproducible measurements.
✔ Hydrofluoric Acid Resistance – 1g/L HF tolerance ensures superior performance and extended electrode lifespan.
✔ Hemispherical Glass Membrane – Up to 10 times more robust than conventional glass membranes, reducing breakage risk.
✔ Silver Ion Trap Reference System – Prevents contamination and blockage caused by silver sulfide, maintaining stable readings.
✔ Long Life Reference System – Ensures extended usability and consistent performance over time.
✔ Blue Gel Electrolyte – Non-flowing design eliminates air bubbles, enhancing measurement consistency.
✔ Swiss Technology & Materials – Designed with proprietary Swiss pH sensor technology for superior durability.
✔ 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-HF and PH8500-HF pH meters.

Warranty:

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