CO Guardian introduced a new
multi-function Carbon Monoxide Detector, Model 552,
at Oshkosh. Though the primary function of the unit is to
monitor CO levels from 30 to 999 ppm, providing an audible alarm if
the count rises above 50 ppm for more than five minutes, there is a
whole lot more to this diminutive collection of computer chips and
sensors. Designed to replace a standard 2-1/4" instrument panel
clock, the Model 552 features a 12-hour and 24-hour format clock
with the additional capability of automatic flight timing and stop
watch functions.
Add to that pressure sensing that triggers an alarm when cockpit
pressure reaches 10,000' and again after 30 minutes above 12,500'
or upon reaching 14,000'. The 85 db alarm can easily be heard, even
with noise-canceling headsets in place. There is also a built in
tone generator for audio panels, which gives additional peace of
mind.
The system keeps track of aircraft voltage, sounding an alarm if
levels exceed high or low levels for the aircraft. A built in
temperature probe and an outside temperature probe keeps track of
both types of data. The instrument also calculates density
altitude, providing readouts on the ground for takeoff analysis.
RS232 output, CO level, cabin pressure and temperature will display
on UPSAT CNX80.
"Technology has reached the point where most instruments can be
multi-tasked," said CO Guardian President, Ash Vij. "Our objective
with the Model 552, was to combine a number of functions that will
provide pilots with useful information. The primary objective,
however, is to avoid the possibility of having lethal or
debilitating levels of Carbon Monoxide accumulate inside the cabin.
You cannot rely on the human nose to sense CO danger... it's
odorless. But with the 552, CO is no longer a threat and the pilot
has a number of other useful benefits at his fingertips."
