Abstract

A calibration unit consists of a housing 1 with a flow duct 2. Arranged at right angles to the duct is a cylinder 4, in which a piston 5 moves by gas pressure with a spring return. The piston rod 6 has a cavity 7 in the end facing the flow duct. Located opposite the cavity, and axially in relation thereto, is an end 9 of a capillary tube 8 which is maintained under vacuum from a gas analyzer. When the piston is actuated, the cavity 7 surrounds the end 9. Calibration is performed using a known gas which drives the piston and is guided further into the cavity 7 through a miniature duct 11 consisting of a measured piece of capillary tube. <IMAGE>
