The LabSen® 211 pH electrode from Apera Instruments is crafted using Swiss sensor technology and materials, providing accurate and reliable measurements for aqueous solutions. Designed for scientific research and quality control applications, it delivers precise pH readings and is compatible with TRIS buffer solutions.

Key Features:

• S-Type Hemispherical Glass Diaphragm: The rugged glass diaphragm ensures quick stabilization of readings (15 to 30 seconds) and is up to 10 times more durable than conventional products, minimizing the risk of electrode damage from impacts.
• Long-Life Reference System: The glass tube, AgCl, and reference silver wire, combined with cotton at the tube's top, prevent temperature-induced reactions, enhancing stability and prolonging electrode life.
• Swiss pH Measurement Technology: Manufactured with advanced Swiss materials for unmatched reliability and precision.
• No Air Bubbles with Gel Electrolyte: The gel electrolyte prevents air bubbles from forming, ensuring consistent readings.
• BNC Connector Compatibility: Works seamlessly with Apera pH meters and other devices using BNC connectors, such as Apera Instruments PH850, PC850, PH8500, PH8500, PH700, PH910, PC910, PH950, PC950, PH800, PH800, PC800, PH820, and PC820.
• TRIS Buffer Compatibility: Suitable for measurements in TRIS buffer solutions.
• Temperature Compensation: For automatic temperature compensation, a separate temperature sensor (e.g., Apera Instruments MP500) is required, or the temperature can be entered manually.

This LabSen® 211 pH electrode comes with a 6-month manufacturer’s warranty.
