KIWK DRAW, Carbon Monoxide 3,000-70,000 ppm, 10 per box, 24-month shelf life

Description

KIWK DRAW, Carbon Monoxide

• 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 vapour reduces the protective layer retention capacity, in particular for hydrocarbons
