Drager Direct Indicating Diffusion Tubes

Using the principles of gas diffusion and colorimetric reaction, Dräger Color Diffusion Tubes allow the user to reliably measure Time-Weighted Average (TWA) concentrations for up to eight hours. An easy-to-use tube holder allows safe tube end removal and secure sampling. Color Diffusion Tubes can be evaluated at any point during a workshift. The calibrated scale printed directly on each tube indicates parts-per-million-hours (ppm-hours). For a TWA reading, simply determine the point where the stain length ends and divide this reading by the total length of sampling time. No pumps, charts, or analyses are needed.
