The CME1-FTG is an 11L 500 ppm Aerosol Carbon Monox
ide Field Test Gas that can be used with the
Macurco CM-E1 and CM-6 CO detectors. This field test gas
allows installers to do a quick functionality test of
the CO sensor. The flow rate of the CME1-FTG is
10 Lpm so you will have about a minute of gas or enough to
test 20-30 sensors.
