The Draeger 6728821 Gas Detector Tube is a colorimetric indicator used with a Draeger tube pump to measure hydrogen sulfide concentrations in air. It serves as a quick, on-site method for determining the presence and approximate level of H2S in workplace environments where gas exposure is a concern. The tube is designed for reliable field use, enabling responders and workers to perform rapid spot checks without complex instrumentation.
Constructed with a glass tube and a break-off tip, this disposable detector provides two standard measurement ranges: 20–200 ppm and 2–20 ppm, with typical test times of about 20 seconds or 3.5 minutes depending on the concentration and pump flow. The packaging indicates a box format containing 10 tubes per box, which supports routine monitoring programs by allowing teams to perform multiple measurements across shifts or work areas. The tube material is glass, consistent with conventional Draeger detector tubes used in industrial hygiene for gas identification and short-term exposure assessment.
When used as part of a Draeger tube pump system, the detector tube must be selected to match the known properties of hydrogen sulfide and the required monitoring range. Operators should follow the manufacturer's workflow for drawing a sample air through the tube to ensure proper contact between the gas and the reactive reagents inside the tube, and to interpret the color change according to Draeger’s guidance. This product is suitable for use in environments where hydrogen sulfide exposure might occur, including confined spaces or areas with potential gas accumulation. Ensure proper handling and disposal of used tubes in accordance with safety protocols and local regulations.
