Mary, Leslie, Ed, et al
The Aviation Consumer did a report on
Monoxide Detectors in their latest issue.
They rated the SafeTest 90 as the best of
the bunch. It is an electrochemical device and costs about $295 retail
and you have to replace the sensor at a cost of $185 every two
years.
The next best one was the AIM696 and
the AIM 935. Both of these are electrochemical sensor designs.
The 696 is $45 and intended for home use. The 935 is $80 and can be
used in vehicles and airplanes. It has to be replaced completely every
3-4 years. It will detect low levels (below 50ppm). They said
the AIM products also have a history of failing but that the work good when
they work.
They also tested the COStar which is a
biomimetric design with a 9 volt battery. It retails for about
$60. Their test indicated that it did not react fast
enough.
They also tested the Dead Spot which costs
about $4-5. The Dead Spot is a biominmetric spot affixed to a 2"
square of plastic. It took about 5 minutes to darken the Dead Spot in
their tests, but not as fast as the electrochemical types. Also, it
won't register low level CO (less than 50ppm) enough to see the spot change
color. But at 100ppm it functions ok apparently. They reported
that the Dead Spot said to replace after 30 days but that the instructions
on the back said to replace every 90 days.
The Quantum Eye is also a biomimetric spot
and costs about $10. It measured up to its advertized claims of
measuring 100ppm in 45 min, 200 ppm in 19 minutes and 400 ppm in 9 minutes,
but they said it was slower to respond than the Dead Stop. It too
didn't detect at 50ppm. It is suppose to have an 18 month life span
but they had no opinion on that claim.
Carbon Monoxide exposure and symptoms are
as follows:
A=5% No
Symptoms
B=10% No
Symptoms
C=15% Slight
headache
D=20%
Headache
E=30%
Drowsy
F=35%
Vomiting
G=40%
Collapse
H=50% Brain damage,
death
They were carefull to point out that
symptoms may vary by person and impairment may occur before
symptoms.
So there you go, for what its
worth.
