Color Metric Diffusion Tubes

Direct-reading Dräger diffusion tubes were developed especially for personal exposure monitoring. These systems do not require the use of a gas detector pump because the contaminant molecules pass into the tube by diffusion processes and in this manner are brought into contact with the reagent systems.
