Enhanced Safety: Sensorcon Industrial CO Carbon Monoxide Monitor - Visual, Audible, and Vibrating Alerts, Waterproof Review

It's only slowly increasing to 8 now, even if I turn it off, go outside and turn it back on, it just keeps going up. Everything in my house is on electricity, and even in the fresh air climbs to the top. Plus the Max button does nothing. I am extremely disappointed.

I was a recipient of carbon monoxide poisoning a few years ago. I was scared to death when I got a terrible headache and the smell of exhaust gas in my car after the service. This detector quickly showed the CO concentration inside my car. Now the mechanic fixes the problem for free.

Nice gadget. Well made, you can tell it's not junk when you pick it up. I use it to check CO levels while driving some of my old cars and also to check CO levels in a garage. It's quite large to carry as a keychain but easily fits in a cup holder. Although we have a carbon monoxide detector upstairs, my wife likes that in the winter when the gas stove and gas water heater are on a lot, she can walk around in the basement and check the carbon monoxide levels.

I use this when I work on my car, travel with AirBNB, hotels and long-distance travel. I always leave it on and carry it in my backpack. I take it out of my backpack when I'm working in the garage or somewhere that doesn't have other carbon monoxide detectors (like my house). Even in my backpack it warns you when you start the car in the garage and let it run for a few minutes. In a backpack, of course, it's not as effective, but it's not useless either. The clip can be removed with a screw.

I'm a paramedic and bought this so I wouldn't have to worry about going into strangers' homes. I've been wearing it every day for about a year and it hardly wears out. So far it works great and is very accurate. The battery life is excellent. I leave it on almost 24/7 and it still runs on the original battery. The vibration and max functions are very useful. It reacts very quickly to carbon monoxide and always ignites within a few seconds. I am very impressed with the durability and build…

The consumer-style, wall-mounted carbon monoxide alarm only checks carbon monoxide exposure over time. However, young children and the elderly may be more sensitive. This device works in real-time and can detect CO leaks, which traditional wall-mounted devices cannot. I would rather know if there is a CO leak from a gas appliance, water heater or stove before spending hours exposed to a CO leak. Cracks in the firebox can only appear after the firebox is fully heated and the crack widens. After…
