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. |

This
tube measures the Sulfide Ion (S2- ), Chloride Ion (CI- ), Mercury (Hg),Iron Ion (Fe2+), Copper Ion (Cu2+)
, Zinc (Zn) , Nickel (Ni), Chromium (VI) Ion (Cr6+),
Ozone (O3) dissolved in water. Place the sample water
in a container. Brake off both ends of the detector tube and immerse
in the sample water is drawn into the tube by capillary action. |
