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 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) The measuring signals can be affected additively by sulphur dioxide and nitrogen dioxide and negatively by chlorine.
4) The measuring signals can be affected additively through acetylene, hydrogen and nitrate monoxide.
5) Certified for 1 to 100 ppm.
6) Certified for 3 to 500 ppm.
7) A table of the cross sensitivities is contained in the Instructions for Use or the data sheet of the respective sensor.
8) For methane, propane and ethylene.
