European Performance Approval
1.
Measuring ranges:
a)
The
Type Examination Certificate
applies to
the measurement of:
•
carbon monoxide in the measuring range
from 0 ppm to 500 ppm
•
hydrogen sulphide in the measuring range of
0 ppm to 100 ppm
b)
The overall indicating ranges are:
•
carbon monoxide: 0 ppm to 1,000 ppm
•
hydrogen sulphide: 0 ppm to 200 ppm
2.
Carbon monoxide measuring values from -5.0 ppm to
+8.9 ppm and hydrogen sulphide measuring values
from -1.4 ppm to +1.4 ppm are indicated during
operation as 0 ppm.
3.

S as +OL. CO over-ranging above
1,000 ppm CO is indicated as +OL.
4.
Sensor cross-sensitivities shall be considered. For
further information, contact BW Technologies by
Honeywell or an authorized agent.
5.
Some types and concentrations of dust in the
measured atmosphere may impair the measuring
function of the gas detector.
