(1) This combustible gas detector unit is NOT designed
for anti-explosive measures. Do not use this unit in an
area where combustible gases can be found.
(2) The following environmental conditions may cause
error in the readings:
ƒ
Large temperature variations
ƒ High wind velocity
ƒ Organic solvents, adhesive vapors, fuel gas and
vesicants. Try to avoid environments filled with
these substances.
ƒ Places filled with too much combustible gas
Note: Although this unit will respond to high levels of
carbon monoxide, it should NOT be used as a detector
for this gas in normal room or working atmospheres. It
is used to pinpoint a leak as described in the operating
instruction.
