Description
KWIK DRAW Methyl Bromide Detector Tubes
- Range: 200 – 8000 ppm with 2 pump strokes
- Range: 2000 – 20000 ppm with 1 pump stroke
- 10 per box
- 24 month shelf life
- No interferences from: hydrogen, methane, ethane, carbon dioxide, as well in concentrations above 50 vol. %, sulfur dioxide, nitrogen dioxide, propane up to 10 vol.%, carbon monoxide up to 1000 ppm.
- Interferences: Higher saturated hydrocarbons, olefinic hydrocarbons, hydrogen sulfide discolor the protective layer from brown to greenish. At least 3000 ppm of olefinic hydrocarbons ( e.g. ethylene) and hydrogen sulfide are retained. Retention is lower for butanes and higher saturated hydrocarbons. (e.g. hexanes) Concentrations of hydrocarbons exceeding the protective capacity may be eliminated by adding a charcoal filter tubes
