GENERAL
The BS-377/WP/A and BS-378/WP/A explosive
gas detectors are used to measure the
concentrations in % L.E.L. (Lower Explosive

autonomous notification/alarm operations in
case there is a leak of liquid on natural gas.
They are used in commercial and small
industrial areas such as professional kitchens
and burner rooms.
The installation must be done by trained

When the detector is exposed to
cleaning agents, silicons and generally
in commercial and light industrial environments
, it is recommended to be calibrated every year
and
its sensor to be replaced every 3 years!
ATTENTION!! DO NOT USE LIQUID

) FOR SENSOR
TESTING
BECAUSE
IT
CAUSES PERMANENT DAMAGE. Use calibration gas up to 50% L.E.L. for this purpose.
(**) = does not cover the gas sensor, if it is exposed to Si, H2S, Pb & halogenated hydrocarbon.
