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
Standard Measuring Range: 0.2 to 2 ppm / 2 to 8 ppm
Reverse activation (n): 1 (1A) / 1 (1A)
Number of strokes n: 5 / 2
Time for Measurement: approx. 8 min / approx. 4 min
Standard Deviation: ± 15 to 20 %
Color Change: light color ──> green
Temperature: 2 to 40°C
Absolute Humidity: < 20 mg/L
Reaction Principle: CH3 Br + H2S2O7 + chromate ──> Br2
Br2 + o-tolidine ──> green reaction product
Cross Sensitivity: 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.
Additional Information: One reverse activationstroke with air or gas sample
