Additional information
Dräger diffusion tubes quantitatively measure the presence of a gas in ambient air. Also called dosimeter tubes or passive reagent tubes, they are particularly popular for TWA controls. Attached to the worker by a clip, the diffusion tube measures the targeted substance throughout the individual's work period (usually 8 hours).
Dräger diffusion tubes require no special tools or know-how to perform measurements. The result can be read directly on the graduated tube.
