- 10 per box
- 24-month shelf life
- No Interferences From: hydrogen, methane, ethane, propane, butanes, carbon dioxide, carbon monoxide, higher saturated hydrocarbons (e. g. hexanes, octanes), olefinic hydrocarbons (e. g. ethylene) aromatic hydrocarbons (e.g. benzene) up to 1 vol% (n=10) or 5000 ppm (n=20), Sulphur dioxide, carbon disulphide up to 200 ppm (n=10) or 100 ppm (n=20), Hydrogen sulphide up to 50 ppm (n=10) or 25 ppm (n=20), Hydrogen sulphide discolors the protective layer from light blue to brown.
- Interferences: Arsine, stibine are indicated with lower sensitivity than phosphine.
