CO warning and measuring for 40$

Re :We can live safer than our ancestors .
Every stover and gas cooker NEEDS to have a Figaro 800 gas sensor,
Platinum hot wire with SnO pelistor .
It measures CO down to 50 ppm in your breathing air !
Calibrate it in a test box with a mixing fan for every combustible gas
or aerosol you like
It detects fuel vapour and CO from a starting car from up to 30 feet away.
Variable alarm setting possible .
Effects of CO at different concentrations.
