Draeger Direct-Reading Diffusion Tubes

Draeger direct-reading diffusion tubes measure a worker's average exposure over 1 to 8 hours without a pump. The tube clips to clothing at breathing height in a diffusion tube holder, and the gas diffuses in on its own, so the reading shows a time-weighted average.

• Passive sampling, no tube pump needed
• Ammonia 20/a-D: 20-1500 ppm (1 h), 0.5-200 ppm (8 h)
• Butadiene 10/a-D: 10-300 ppm (1 h), 1.3-40 ppm (8 h)
• Trichloroethane 50/D: 50-600 ppm
• Use with the Draeger holder for diffusion tubes
