Product description
Drager Short Term Detection Tubes - Methyl Bromide 0.2/a
These Drager short-term detection tubes are for Methyl Bromide (0.2/a) and have a measurement range of 0.2 to 2 ppm.
They may also detect a range of other substances including vinyl chloride or carbon tetrachloride (< 2 ppm no indication).
It’s important to note that 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.
Key Features
- Designed for short-term, on-the-spot measurement
- Can take between 10 seconds to 15 minutes to gather a reading
- Applications may include concentration fluctuations in the workplace, measurement of contaminants in breathing zone, and confined spaces
- Can be used as pre-entry checks
