Methyl Bromide Detection Tubes 0.1/a (0.1 - 50 ppm)

For short-term measurements more than 160 Draeger-Tubes are available to measure the spot concentrations of specific gases. Measurement usually takes between 4 seconds and 15 minutes. The tubes are used either manually with the Draeger-Tube Accuro Pump or automatically with the Draeger X-act 5000.

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

In the presence of perchloroethylene or trichloroethylene, a methyl bromide measurement is not possible! 

Sulfuryl fluoride, phosphine, ethylene oxide, ammonia, hydrogen cyanide, chloropicrin and formaldehyde are not indicated below their threshold values. 

2 ppm ethylene dibromide is indicated with approximately the same sensitivity. 

0.5 ppm vinyl chloride is indicated with a reading of less than 0.1 ppm. 

2 ppm 1.1 dichloroethylene is not indicated and 20 ppm 

1.2 dichloroethylene is indicated with a low reading of 3 ppm.
