1) The technical manual and instructions for use/data sheets for the utilized sensors and the PC software CC-Vision for Dräger X-am 2500 can be downloaded from the product page of the X-
am 2500 on the following website: www.draeger.com
2) For decreasing concentrations, the adjustment time for nonane is 50 seconds.
3) Alkanes from methane to nonane, LEL values in accordance with EN 60079-20-1. At flow speeds of 0 to 6 m/s, the deviation of the reading is 5 to 10 % of the measured value. For an
adjustment to propane, the deviation of the display in the range of 80 to 120 kPa can be up to 8 %LEL.
4) Certified measuring range for: 0 to 5 vol.%
5) Certified measuring range for: 0.4 to 100 ppm
6) Certified measuring range for: 3 to 500 ppm
