Mesh Electrodes

The alloy of platinum with 10% iridium has been proven as an outstanding material for electroanalysis. Its excellent electrical conductivity and remarkable resistance to chemical influences make it the preferred choice for electrode applications. As standard, ÖGUSSA supplies electrodes in designs by Fischer, Winkler, Wölbling and Schöniger. Other shapes can also be produced if desired. Fischer electrodes are generally sandblasted; all others only at the request of the customer. Repairs are possible on request.
