| 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. |
