Abstract

A sampling device for sampling a corrosive medium, is comprised of an inner tube with a flange and an outer tube with a flange, both made of a synthetic material; a metallic tube with flange is interposed between the inner and outer tubes to serve as armoring in this coaxial synthetic tube arrangement; the flange of the metal tube grips around the flange of the outer tube; and a recess in one of the synthetic flanges exposes a portion of the metal flange of the intermediate tube as a support surface for a fastening structure.
