Measuring Function
The use of Gas Detection Systems for explosion and health protection requires special care.
Besides qualified support of ExTox and the detailed information in the Instruction Manuals
as well as Technical Data Sheets (

DB) there are several guides to assist you for the safe
use and operation of Gas Detection Systems. These guides deal with the selection, installa-
tion, initial operation and regular maintenance.
Furthermore there could be national regulations. In Germany there are for example the
guidelines of the Berufsgenossenschaften BGI 518 and BGI 836 obligatory for certain appli-
cations.
