Cross sensitivities
1) The Technical Handbook and Instructions for Use/data sheets for the sensors used and the PC software CC-Vision for Dräger X-am 5600 are available on the product page of the X-am 5600 at the following
Internet address: www.draeger.com. See also attached Instructions for Use and Data Sheets of the sensors used.
2) Certified for 1 to 100 ppm.
3) Certified for 0.4 to 100 ppm.
4) The measuring signals can be affected negatively by ethane, ethene, ethine, carbon dioxide and hydrogen.
5) The measuring signals can be affected additively by sulphur dioxide, nitrogen dioxide and hydrogen and negatively by chlorine.
6) 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
7) A table of the cross sensitivities is contained in the Instructions for Use or the data sheet of the respective sensor.
