Description
KWIK DRAW Sulfur Dioxide Detector Tubes
- Range: 2 – 30 ppm with 3 pump strokes
- Range: 0.5 – 7 ppm with 10 pump strokes
- 10 per box
- 24-month shelf life
- No Interferences From: hydrogen, methane, ethane, propane, butanes, carbon monoxide, carbon dioxide, higher saturated hydrocarbons (e. g. hexanes, octanes), aromatic hydrocarbons (e. g. benzene) up to 1000 ppm, hydrogen sulfide up to 100 ppm (n=3) or 40 ppm (n=10), Hydrogen sulfide will be retained by the protective layer changing its color (light blue → brown). Do not use the detector tube if protective layer has totally change its color, hydrogen chloride up to 25 ppm (n=3) or 10 ppm (n=10).
- Interferences: Chlorine, ammonia, nitrogen dioxide, olefinic hydrocarbons (e. g. ethylene) are not indicated but possibly will shorten indication stain of sulfur dioxide even when concentrations correspond to the measuring range of detector tube.
