Description
KWIK DRAW Carbon Monoxide Detector Tubes
- Range: 3000 – 70000 ppm with 1 pump stroke
- 10 per box
- 24-month shelf life
- No Interferences From: Hydrogen, methane, ethane, carbon dioxide, sulfur dioxide, nitrogen dioxide, propane up to 10 vol.%
- 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 tube Ads (804403), Water vapor reduces the protective layer retention capacity, in particular for hydrocarbons
