• Hey Guest,

    As you know, censorship around the world has been ramping up at an alarming pace. The UK and OFCOM has singled out this community and have been focusing its censorship efforts here. It takes a good amount of resources to maintain the infrastructure for our community and to resist this censorship. We would appreciate any and all donations.

Will this type of carbon monoxide work with a gas mask?

I don't think so. A lot of the calibration gasses are mixtures with very little CO in them. I see ones for 60 ppm and 100 ppm, but those amounts are too small— way less than half a percent.
