With our patented °AirRay electrode technology we have overcome current limitations of electrodes.
Based on our laser-aided manufacturing process we can design and manufacture electrodes according to your actual requirements – in any geometrical shape, with hundreds of contacts, and for numerous applications.
All our products are engineered and manufactured in Germany.
