Draeger CH28201 Gas Detector Tube, Hydrogen Sulfide + Sulfur Dioxide 0.2%/A, 10/Box

The Draeger CH28201 Gas Detector Tube is designed for quick, on-site measurement of airborne hydrogen sulfide and sulfur dioxide using Draeger’s glass tube technology. Packaged as a 10-tube box, this configuration supports multiple short-duration readings with a standardized measurement window, typically completed in about two minutes per test. The tube’s glass construction and break-off tip are consistent with Draeger’s traditional colorimetric tube method, allowing the user to draw a sample with a compatible tube pump and interpret results based on the indicated measurement range.

Each tube is calibrated to detect a combined H2S and SO2 response within a standard range of 0.2% to 7% vol., making it suitable for assessing short-term exposure levels in environments where these gases may be present. The 0.2%/A specification reflects the tube’s target sensitivity, and the 2-minute read time provides a rapid indicator for field decisions. The glass tube format and break-off tip are integral to the method’s reliability, ensuring a controlled break and collection of the sample for colorimetric reaction visible as a color change along the tube’s length.

To use, pair the CH28201 tubes with an appropriate Draeger tube pump and follow the standard operating procedure for Draeger colorimetric tubes. This includes ensuring proper handling of glass components, timely reading after the sampling interval, and proper disposal of used tubes. The package sizing (Box, 10 tubes) supports easy stocking and consumable management for facilities performing periodic gas monitoring in maintenance, safety, or regulatory-compliance workflows.
