Stainless steel 1.4404/graphite/and see filter Optional coating with SilcoNert® 2000 *
*The SilcoNert® 2000 coating forms a layer of hydrogenated, amorphous silicon on the surfaces of the measuring gas probe that
are in contact with media. It is applied by chemical vapour deposition (CVD), which creates a uniformly thin layer on the surface.
SilcoNert® 2000 is temperature-resistant up to 400 °C, chemically inert and hydrophobic. The coating is resistant to many chemically corrosive liquids. If you are unsure about the suitability for specific gas matrices, please contact Bühler Technologies
GmbH.
