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.
For the CO
2
tube (67 28521), there is an
option to adjust the test volume up by a
factor of two to increase the number of
scale points. This option can be set within
the setup menu as shown here.
When entering the test results into the
tester, the tube reading shall automatically
be divided by two, to reflect the actual
reading as shown here.
