Methyl Bromide Detection Tubes 0.2/a (0.2 - 8 ppm)
For short-term measurements more than 160 Draeger Tubes are available to measure the so called spot concentrations of specific gases.
A wide range of different gases and vapors can be detected and measured, such as:
- Determining and measuring concentration peaks
- Measuring personal exposure in the inhalation area
- Detecting leaks in pipelines, gas installations etc.
- Air analysis in sewers, shafts and confined spaces

||Vinyl chloride or carbon tetrachloride: < 2 ppm no indication. Methyl bromide cannot be measured in the presence of perchloroethylene or trichloroethylene. Sulfuryl fluoride, phosphine, ethylene oxide, ammonia, hydrocyanic acid, chloropicrin and formaldehyde below their AGW/TLV values are not indicated. Ethylene dibromide is indicated with 1.2 times its sensitivity.
