SF6 decomposition analysis Draeger

Also known as dosi-tubes, dosimeter tubes measure a quantity of gas on a defined period (8 hours usually) to monitor time weighted average measures (TWA) of present gases and substances. Dosimeter tubes are widely used to monitor concentrations of formaldehyde, benzene and carbon dioxide in buildings open to the public.. Time-weighted detector tubes are small and lightweight and feature a clip ...
