Carbon monoxide detectors are essential pieces of safety equipment for any business or office with gas-powered devices. These tester are designed to let you know when CO levels reach unhealthy proportions. Multipacks are available, letting you buy enough for your entire office building at one time.

LED Security
LED lights make it easy to tell if your detector is getting power. Different colored or flashing lights alert you to possible carbon monoxide dangers.

Battery Backup
Units that can be plugged into wall outlets let you place testers conveniently next to gas stoves or other appliances. These models also feature battery backup, so you don't have to worry about missing the alarm if the power goes out.

Convenient Testers
Carbon monoxide detectors come equipped with easy-push test/reset buttons, letting you make sure your unit is still working properly whenever you want or as part of your regular maintenance schedule.
