Geiger CO is a key fob-sized unit that provides real time alarm when carbon monoxide levels are dangerously high. The auto calibrating unit includes an aural alarm and a visual LED scale.
In contrast to competitive products, GEIGER CO is much smaller, more responsive and rechargeable. It is designed to run off an internal USB rechargeable battery.
Geiger CO is designed to be attached to a keychain, but because of its small size, it can be hung anywhere, which makes it desirable for anyone who travels (for use in truck cabs or hotel rooms, for example). According to our market research, this is the smallest, most portable, most usable CO monitor available, and it is reasonably priced.
