Components
1.4.1
The primary components are shown in Figure 1.
The instrumentation is enclosed in a non-metallic case.
The monitor system includes the instrument case,
filter/regulator, ten feet of 1/8" ID x 1/4" OD tubing with
adaptor fittings, a cylinder of 10 PPM (parts per million)
test gas, and calibration connector which includes the
connector valve and tubing.
1.5
Operating Principles
1.5.1
The CMS monitor samples respiratory air from a
breathing-air source. The air to the respirator does not
actually pass through the monitor. This enables one
monitor to detect CO (carbon monoxide) in the entire
breathing-air system, not just in the air to a single
respirator.
When the CMS is correctly installed and
maintained, it monitors the level of carbon
monoxide in the air supply. The instrument is a
monitoring device; it DOES NOT remove or
convert carbon monoxide.
