Dont rely on to detect danger levels
I am a physician. 50ppm CO is the OSHA limit for 8hr exposure in workplace. 800ppm of Carbon Monoxide is lethal for an adult within 1 hr.

Great investment
Installed several of these in my house to check for carbon monoxide around the area. Fortunately, none of them went off.
