COi Sensor

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 COi 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 COi from a starting car from up to 30 feet away.

Variable alarm setting possible .

Effects of COi at different concentrations.
