- FOR AIRLINES BELOW 40 BAR THE PRESSURE DEWPOINT TO BE 5°C
BELOW THE LIKELY LOWEST TEMPERATURE. WHERE THE LIKELY
LOWEST TEMPERATURE IS NOT KNOWN THE PRESSURE DEWPOINT
SHOULD NOT EXCEED -11°C.
- FOR HIGH-PRESSURE CYLINDERS THE FOLLOWING UPPER LIMITS
APPLY: - 40 TO 200 BAR = 50MG/M³, ABOVE 200BAR = 35MG/M³
- FOR HIGH-PRESSURE CYLINDER CHARGING COMPRESSORS THE
UPPER LIMIT = 25MG/M³
A reddish brown discoloration will show the extent of the water content, which is read from the
scale printed on the tube in mg/m³.
When using the 50-2000 range setting, the tube reading is multiplied by a factor of 10, i.e. a
tube reading of 150mg/m³ becomes 1500mg/m³. To establish the pressure dewpoint refer to
the graph on the back of the Safe-Air Tester Result Sheet.
Carbon Dioxide (CO
2
) (67 28521)
REQUIREMENT
- MAXIMUM READING OF 500 PPM.
The media in the detector tube will discolour to show the presence of carbon dioxide. The total
length of the discoloration read from the printed scale at that point is a measure of the
concentration in parts per million.
Carbon Monoxide (CO) (67 28511)
REQUIREMENT - MAXIMUM READING OF 5 PPM.
The media will discolour to show the presence of carbon monoxide in the air sample. The total
length of the discoloration is the measure of concentration read directly from the scale in parts
per million.
