Guys, if you're going to spend on a box of 10 or 50 co stickers @$3.50 then why not spend £100 on a personal CO sensor that gives a ppm reading. In the UK Casella and Kane may supply such. I'm sure theer are plenty of manufacturers/importes in the US- checkout plumbers merchants these guysd use tehm when setting up gas or Oil furnaces.

And a multitude of other sensors. Don't know their prices yet. But I think the really cheap sensors are a one-time, throw-away thing, once they've been exposed they don't clear themselves. These would seem to be of limited usefulness, however, when what we really need is something to monitor the actual amounts of unburned CO so as to facilitate the adjustments in stove design. I guess I'm not personally over concerned about the dangers of CO (although I am well aware of them, and have been), I've developed over the years a rather high sensitivity to noxious vapours of all types -- simply riding a bicycle or walking past someone smoking, for instance, or even being in a store with lots of chemical smells --- ugh! -- Harmon Seaver CyberShamanix http://www.cybershamanix.com - Gasification List Archives: http://www.crest.org/discussion/gasification/current/ Gasification List Moderator: Tom Reed, Biomass Energy Foundation, Reedtb2@cs.com www.webpan.com/BEF List-Post: <mailto:gasification@crest.org> List-Help: <mailto:gasification-help@crest.org> List-Unsubscribe: <mailto:gasification-unsubscribe@crest.org> List-Subscribe: <mailto:gasification-subscribe@crest.org> Sponsor the Gasification List: http://www.crest.org/discuss3.html - Other Gasification Events and Information: http://www.bioenergy2002.org http://solstice.crest.org/renewables/biomass-info/gasref.shtml http://solstice.crest.org/renewables/biomass-info/ - Gasification List Archives: http://www.crest.org/discussion/gasification/current/ Gasification List Moderator: Tom Reed, Biomass Energy Foundation, Reedtb2@cs.com www.webpan.com/BEF List-Post: <mailto:gasification@crest.org> List-Help: <mailto:gasification-help@crest.org> List-Unsubscribe: <mailto:gasification-unsubscribe@crest.org> List-Subscribe: <mailto:gasification-subscribe@crest.org> Sponsor the Gasification List: http://www.crest.org/discuss3.html - Other Gasification Events and Information: http://www.bioenergy2002.org http://solstice.crest.org/renewables/biomass-info/gasref.shtml http://solstice.crest.org/renewables/biomass-info/
