CO Guardian upgrades its best selling model 352 to the 353. Model 353
has a brand new sensor that can detect CO as low as 1 Part Per Million
(PPM) to 999 PPM. This unit now comes standard for interfacing CO levels
display on the G1000, GNS480 and other Multi- function displays. The 353
now has a built in pressure sensor that compensates for altitude. These
units can be mounted on the panel or remotely. The primary function of
the unit is to monitor CO levels from 01 to 999 ppm. If the CO level above
50 ppm within five minutes, an audible 85db alarm will sound. But there
is allot more to this new warning system. Bonus safety feature is pressure
sensing, which constantly monitors cabin pressure, and triggers an additional
light when cockpit pressure reaches 10,000’ for 10 seconds 12,500
for 10 seconds) and 14,000 feet (Continuously). Even when you have your
noise-canceling headsets in place, you will be able to hear the 85db alarm.
