Know The Facts About Your Carbon Monoxide Tester Before You Buy
Carbon Monoxide Tester
A carbon monoxide tester is your first line of protection against potentially deadly carbon monoxide leaks in your home. But before you by one, you need to know how they work, and what types there are to choose from.
There are three main types of carbon monoxide testers, each with a different type of sensor. The first, and original, type of sensor is metal oxide semi-conductor, or MOS. Units with this type of sensor don’t require batteries, as they need to be plugged in. The metal oxide, usually tin, is heated and it will react with carbon monoxide to read the levels in your home. Most of these units come with battery back-up, some up to 20 hours. If you choose this type, check and see how long the battery back-up is, and what sort of maintenance you need to do regarding changing batteries.
The second type of carbon monoxide tester has biomimetic sensors. These sensors are discs coated with a special gel that turns dark when carbon monoxide comes into contact with them. The change in color is what triggers the alarm. These are generally less expensive. They can be plug in units, or battery operated, which gives you more leeway in where you place them in the house.
The third type of carbon monoxide tester is electrochemical. Carbon monoxide in the air will cause a chemical reaction with the sensors, which creates an electric current that triggers the alarm. These are the most sensitive monitors, and as such tend to be the most expensive. They give precise readings even at low levels, while other types tend to only read higher levels. Many have a memory feature that records peak levels over time, and you can access this information by pressing a button. Some also have a continuous digital readout, which lets you see at a glance what your levels are like. Finally, many of this type will alert you when the sensors need to be replaced…a lifesaving feature.
No matter which type you choose, carbon monoxide testers must be placed properly in order to protect you. The best place, of course, is one where you will hear it even if you are sleeping. If you have several bedrooms, mount your detector in the hallway so all rooms will hear it. If you have bedrooms in other parts of the house, you should install additional units there as well. Avoid areas of high humidity, and keep them at least 6 feet away from cooking and heating appliances and areas of low air circulation.
Along with your carbon monoxide tester, you need to have a proper maintenance plan and emergency plan, so that you both prevent problems from happening, and know what to do when they do occur. With all that in place, you and your family are well equipped and have a better chance of staying healthy and safe.
