DRAEGER DIFFUSION TUBE AMMONIA 20/A-D

Direct-reading Draeger diffusion tubes are used to determine average concentrations or time-weighted averages over a period of 1-8 hours. The direct-reading Draeger-Tubes are attached to the clothing with a mount at breathing height as passive measuring system, thus without using a Draeger tube pump. According to the principle of diffusion the harmful molecules enter the diffusion tube. The offered Draeger-Tube has the following standard measuring ranges:
20-1500 ppm/1 h
0.5-200 ppm/8 h
Measurements: 10
