The Dräger Diffusion tubes are direct reading systems used for the determination of time weighted average concentrations over the duration of one to eight hours.
Easy handling The 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 Dräger 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.
The Dräger Pac® 8500 single-gas detection device is a reliable and precise instrument even under the toughest of conditions. Measured data can easily be transmitted into the Dräger Gas Detection Connect system via Bluetooth®. The device can be equipped with a hydrogen-compensated CO sensor or a Dräger dual sensor. This gives you the option of measuring two gases at once: H2S with CO, H2S with O2 or O2 with CO.
