Long-Term (time-weighted) measurement detector tubes

 


Overview

The dosimeter tube method utilizes the principle of gas diffusion. Using the holder (Dosi-Tube Holder No.710-3 pcs. in package) attach the tube to the breathing zone of the worker. (i.e.,lapel) and measure individual exposure Time-Weighted-Average (TWA). Or it can be installed in work areas to act as an area monitor for TWA measurement. The chemical reagent and diffusion barrier are positioned in the detector tube to give consistent gas diffusion uptake by the tube and clear color change. No pumps, paper charts, secondary operations or laboratory analysis is required. For more details, please see attached tube list.
