Operating Instruction
Safety notes
Even if a concentration under the LEL is
measured in a certain position of the device
in the room, e.g. at normal working height,
it is possible that there may be a higher con-
centration in the explosive range in other
parts of the room or the building.
Gas testing method
The gas testing method with forming gas 5/95
(5% hydrogen in nitrogen) was developed to
locate the smallest leaks, those that cannot
be located using acoustic methods. The selec-
tion of hydrogen gas means there is no inter-
ference from other gases such as methane or
sludge gas. Please contact Herth+Buss for a
detailed description of the method, including
practical examples if required.
