Draeger CH20501 Gas Detector Tube, Ammonia 5/a, 10/Box

The Draeger CH20501 Gas Detector Tube is a glass-waste, single-use indicator tube designed for rapid, on-site detection of ammonia concentrations in air. Used in conjunction with a Draeger tube pump, this tube provides a hands-on method for measuring ammonia levels by drawing a known volume of air through the tube, where the chemical reagents produce a color change proportional to ammonia concentration. The product is packaged as a box containing ten tubes, making it suitable for periodic testing across multiple samples or work shifts.

Construction details include a glass tube with a break-off tip, enabling simple, clean activation. The tube is specified for two measurement ranges: a lower range of 5–70 ppm and a higher range of 50–700 ppm, with a typical measurement time of approximately one minute and six seconds. The feature set supports field use where quick decisions about gas presence are needed, without requiring a laboratory or power source. This tube is intended for use specifically with ammonia detection, denoting a targeted approach to monitoring ammonia exposure in industrial settings.

Practical use considerations include ensuring correct selection of the measurement range for the anticipated ammonia concentration and following standard operating procedures for Draeger tube sampling. The box quantity of 10 tubes provides adequate coverage for routine checks or intermittent sampling; users should maintain proper storage conditions to preserve reagent integrity and refer to manufacturer guidelines for disposal after use. This product is categorized as a gas detector tube, suitable for workplaces where ammonia monitoring is part of hazard assessment and control programs.
