Test station i.e. calibration station, for portable gas measuring device that is worn by user in field exposed to harmful gases, has seal fixed at plastic seal carrier, which is releasably attached on swingable flap

摘要

The test station has a retainer receiving a portable gas measuring device. A swingable flap covers a region of gas inlet openings of an exposed surface of the gas measuring device received in the retainer. A seal arranged at the flap surrounds the region of gas inlet openings and seals the region of the gas inlet openings against an environment in a covering position. A conduit is extended from a test gas supply to a region inside the seal to supply test gas to an area surrounding the seal. The seal is fixed at a plastic seal carrier (2), which is releasably attached on the flap. The seal carrier is designed as a corner piece. An independent claim is also included for a combination of a test station and a portable measuring device.
