APPENDIX 3
Reading the Draeger Oil Impactor and Chemical Reagent Tubes
Oil Impactor
With a standard measurement range of 0.1 to 1.0 mg/m
3
the Impactor has a limit of
detection of 0.05 mg/m
3
. The Impactor features a series of 3 horizontal lines, each
formed by a series of precision manufactured nozzles. These horizontal lines of
nozzles are calibrated to a different concentration of oil. When air is passed through
these nozzles any oil present in the air is deposited on the glass plate prior to the air
being exhausted by vents around its circumference, this allows the user to easily and
quickly identify minute quantities of oil.
For tests that pass with an oil concentration of less than 0.05mg/m
3
, the screen will
remain blank. For tests above that read as follows:
The bottom line represents an oil concentration of 0.1 mg/m
3
. When the oil deposited
forms a continuous line then the concentration is in excess of 0.1 mg/m
3
. The middle
line represents a concentration of 0.5 mg/m
3
, again when the oil deposited forms a
continuous line the concentration is in excess of 0.5 mg/m
3
. The top line represents a
concentration of 1.0 mg/m
3
, again when this forms a continuous line the concentration
is in excess of 1.0 mg/m
3
.
