KWIK DRAW Dichloromethane-A Detector Tubes

  • Range: 100 ppm with 5 pump strokes
  • Range: 500 ppm with 5 pump strokes
  • 10 per box
  • 12 month shelf life
  • No Interferences From: methane, carbon dioxide, hydrogen, ethane, carbon tetrachloride, fluorinated methanes, fluorinated ethanes up to1 vol.%, ammonia, sulfur dioxide, chloromethane up to 2000 ppm, olefinic hydrocarbons (e.g. ethylene), aromatic hydrocarbons (e.g. benzene), nitric oxide,
    nitrogen dioxide up to 500 ppm, propane and higher saturated hydrocarbons (e.g. hexanes, octanes), hydrogen sulfide up to 200 ppm, chlorine, hydrogen, chloride, hydrogen cyanide, phosgene up to 50 ppm.
  • Interferences: Acetylene, hydrogen disulfide, easily decomposable halogenated hydrocarbons (e.g. trichloromethane,trichloroethylene, chlorobenzene), will be indicated. The sensitivity varies. In the presence of these substances and other oxidizable gases and vapors part of conversion layer will be consumed. Indication of dichlormethane then may be lower than actually present. High concentrations of those accompanying substances discolor conversion layer from brown to greenish. Do not use detector tube in this case. Carbon monoxide will be indicated without affecting conversion layer.
