Glass‐body pH Electrode Apera LabSen 211
The Glass‐body pH Electrode Apera LabSen 211 is a high-precision glass-body pH electrode engineered for laboratory professionals who require accurate, stable, and fast pH measurements. Built with Swiss sensor technology, it is ideal for routine and advanced pH testing across a broad range of samples.
Features
High Accuracy and Fast Response
Thanks to its low membrane resistance (<150MΩ) and high-quality half-ball glass membrane, the LabSen 211 ensures rapid stabilization and high measurement accuracy, even in low-ion strength or cold samples.
Long-Life Reference System
The electrode is equipped with a long-life reference system that significantly extends the probe’s durability and reduces drift. This ensures consistent and reliable results over extended usage periods.
Ceramic Junction with Stable Electrolyte
With a ceramic junction and filled with 3M KCl electrolyte, this electrode offers excellent ionic conductivity. As a result, it maintains measurement stability across a wide pH range from 0 to 14.
High-Temperature Compatibility
The LabSen 211 operates over a broad temperature range of –5 to 100°C (23 to 212°F), making it suitable for various laboratory and industrial applications, including warm or acidic samples.
Universal BNC Connector
Fitted with a standard BNC connector, the electrode is compatible with most benchtop and portable pH meters, providing easy integration into existing lab setups.
