Apera Instruments LabSen® 213 Combined pH Electrode

Apera Instruments LabSen® 213 Combined pH Electrode

The Apera Instruments LabSen® 213 Combined pH Electrode is a high-quality pH electrode with an integrated temperature sensor, designed for precise and stable pH measurement across various aqueous solutions. This electrode is suitable for scientific research, laboratories, water quality testing, quality control, and various routine pH measurement applications.

The LabSen® 213 uses Swiss pH sensor technology and pH measurement materials with a LabSen S-Type Hemispherical Glass Diaphragm. This hemispherical glass membrane has low resistance as well as a robust construction, enabling it to produce stable readings in approximately 15–30 seconds.

The LabSen® 213 features a patented combined pH and temperature structure. The temperature sensor element is placed in a separate chamber below the pH glass membrane and is equipped with a heat-conducting medium. This design allows temperature measurement to occur up to 40% faster, helping improve response speed and measurement stability.

The electrode uses a gel electrolyte that helps prevent the formation of air bubbles in the sensor system. The LabSen® 213 is also compatible with TRIS buffer solutions and uses a BNC connection for the pH signal and RCA (Cinch) for the temperature sensor.

The BNC compatibility allows the electrode to be used with various Apera Instruments pH meters such as the PH850, PC850, PH8500, PC8500, PH700, PH910, PC910, PH950, PC950, PH800, PC800, PH820, and PC820. The integrated temperature sensor uses an RCA connector, and its compatibility with devices from other manufacturers needs to be adjusted beforehand.
