The Drager Diffusion Tubes are Tubes that are developed for personal exposure monitoring. The Diffusion Tubes do not require a Gas Detector Pump, because the contaminant molecules pass into the Tube by diffusion processes and are brought into contact with the reagent systems. The Drager Diffusion Tubes are used for the determination of time weighted average concentrations over the duration of 1 to 8 hours.
Benefits:
Easy handling
The Drager Diffusion Tubes are very easy to handle. Since these are passive measurement systems, relying on the diffusion of contaminant molecules in air, they do not require a pump. The Diffusion Tubes are used with a plastic holder which is attached to the clothing (shirt collar, pocket, etc.).
Low concentrations
The Draeger Diffusion Tubes are able to measure very low concentrations. The contaminant molecules pass into the tube by diffusion processes and are brought into contact with the reagent systems.
Direct reading
The measurement result can be read directly on the scale printed on the Diffusion Tube following the length of the discoloration.
