Cross sensitivities
1) The Technical Handbook and Instructions for Use/data sheets fort he sensors used and the PC software Dräger CC-Vision for Dräger X-am 5600 are enclosed on CD. See also attached Instructions for
Use and Data Sheets of the sensors used. The Instructions for Use/data sheets for the sensors used can also be downloaded at the following Internet address: www.draeger.com.
2) The instrument responds to most combustible gases and vapours. The sensitivities differ depending on the type of gas. We recommend a calibration using the target gas to be measured.
3) Certified for 1 to 100 ppm.
4) Certified for 3 to 500 ppm.
5) The measuring signals can be affected negatively by ethane, ethene, ethine, carbon dioxide and hydrogen.
6) The measuring signals can be affected additively by sulphur dioxide, nitrogen dioxide and hydrogen and negatively by chlorine.
7) The measuring signals can be affected additively by ethine, sulphur monoxide and carbon monoxide. Increased hydrogen concentrations within the measuring range of the XXS H
alarms by the additive affect with the XXS H
8) The measuring signals can be affected negatively by acetylene, hydrogen and sulphur monoxide.
9) For methane, propane and ethylene.
10) For methane, propane and nonane, each with 0-100 %LEL.
11) Certified for 0,01 to 5,00 vol.-% CO .
