Draeger CH28301 Gas Detector Tube, Phosgene 0.25/c, 10/Box

The Draeger CH28301 gas detector tube is a single-use chemical analysis indicator designed for measuring phosgene concentrations in air. Packaged as a box containing ten tubes, each tube is designed to indicate phosgene within a calibrated range and is intended for use with a Draeger tube pump. The primary function is to provide a quick, colorimetric readout that reflects gas presence and approximate concentration after a short measurement period, enabling on-site decision making in environments where phosgene exposure is a concern.

Construction and distinguishing features include a glass tube with a break-off tip, standard for colorimetric color-change tests, which enables handling and breaking of the tube to initiate the measurement. The standard measurement range for this product is 0.25 to 5 ppm, with a typical measurement time of 1 minute, allowing rapid screening in industrial settings. The format and packaging are compatible with Draeger’s established line of tube pumps, and the box contains 10 tubes per box to support routine testing workflows.

These tubes are suitable for use in environments where phosgene exposure monitoring is required, particularly in laboratories, chemical processing, and manufacturing facilities where phosgene use or release might occur. Practical considerations include ensuring correct tube selection for the target gas and adhering to the manufacturer’s protocol for tube handling and interpretation of results, as well as replacing tubes on a schedule aligned with sampling frequency and regulatory requirements. The product is categorized as a gas detector tube and is identified by the Draeger part number CH28301, aligning with Draeger’s documented tube-based gas analysis method.
