LabSen® 843 combined pH/temp. electrode for strong base solutions

The LabSen® 843 pH electrode from Apera Instruments is manufactured using proprietary Swiss sensor technology and materials. It was specially developed for measuring strongly basic solutions (10-14 pH) and has an integrated temperature sensor, which enables automatic temperature compensation for pH measurements.

LabSen HA Glass Membrane – The LabSen 843 pH electrode uses a special glass membrane that provides better accuracy and reproducibility in strong base solutions while minimizing alkali error. The hemispherical glass diaphragm is robust and built to be highly shock resistant (up to 10 times more robust than conventional products), significantly reducing the likelihood that the electrode will break upon impact.

Silver Ion Trap Reference System – In addition to the Long Life Reference System, a silver ion trap is incorporated into the LabSen 843 pH electrode to prevent blockage or contamination of the diaphragm by silver sulfide.

• Proprietary pH sensor technology and materials from Switzerland
• Especially for pH measurement of strongly basic solutions (10-14 pH) with minimized alkali error
• Silver ion trap reference system prevents contamination of the electrode
• Glass membrane up to 10 times more robust than conventional products
• Blue gel electrolyte, does not flow and does not cause air bubbles
• Integrated temperature sensor enables automatic temperature compensation

The electrode uses a BNC connector that is compatible with all pH meters that use BNC connectors, such as Apera Instruments PH850, PC850, PH8500, PC8500, PH700, PH910, PC910, PH950, PC950,PH800, PH800, PC800, PH820 and PC820. The integrated temperature sensor is connected with an RCA connector (Cinch) and is not compatible with all measuring devices of other manufacturers.

This electrode has a 6-month manufacturer’s warranty.
