The 6 Best CO detector

Table of Contents:

Every year in Germany, several thousand emergency doctor calls are made as a result of carbon monoxide poisoning. The dangerous breath poison is not to be seen, not to be tasted and not to be smelled and is considered therefore as soundless killer. CO gas is produced when fuels containing carbon such as natural gas, wood, oil or charcoal burn with insufficient oxygen supply. Defective gas heaters and heating systems as well as insufficiently maintained stoves are often responsible for the lethal gas outflow. Patients initially experience only mild symptoms such as headaches or dizziness. As a result, CO gas leads to fainting and suffocation. To avoid accidents with CO gas, a CO detector should be installed in every household. It registers minute amounts of carbon monoxide in the air we breathe and alerts the residents like a fire alarm with a loud signal tone. This can save lives in an emergency.

The basic technical principle is the same for all CO detectors: an electrochemical sensor registers the smallest quantities of the hazardous gas in the ambient air. The amount of registered carbon monoxide is decisive for the alarm. Recommended detectors such as the Binwo CO detector are based on the values of the EU standard EN 50291, which defines when an alarm is to be triggered. The detectors use the PPM measuring unit (“parts per million”). At a value of 50 ppm, the CO detector triggers an alarm after 60-90 minutes. At 100 ppm already after 10-40 minutes. Symptoms such as dizziness, nausea and vomiting may occur. For life-threatening values above 300 ppm, the alarm sounds within 3 minutes. Some devices are additionally equipped with a pre-warning function. As soon as the CO concentration increases even slightly, this can be seen on the optical display.

To ensure protection against CO gas, homeowners must replace the detectors after a few years. The reason for this is the electrochemical sensors, which age over time and can lose their functionality. Depending on the manufacturer, the devices have a maximum service life of five to ten years. An equally important point is energy supply. Cheap detectors rely on commercially available AA batteries. After some time, maintenance is required to replace the batteries. Most devices, however, give an early warning tone that the batteries are about to run out. CO detectors with a 10-year battery are more convenient. An example of this is the KIDDE CO alarm X10-D. It is equipped with a lithium battery according to EN 50291 and usually does not require any further maintenance after installation.

The installation of CO-warners is usually problem-free. Some manufacturers recommend placing the devices in a room – for example on a shelf. Other devices, such as the X-Sense CO03D CO detector, are suitable for wall mounting. The Warner can be securely attached with two screws. Take care not to install the appliance directly on a window or in a bathroom with shower. False alarms can occur in these places.

CO detectors differ in their technical equipment and their additional functions. In addition to typical CO detectors, which only measure the carbon monoxide content, manufacturers such as X-Sense also offer combined devices with the DS51. They are also equipped with a photoelectric sensor that detects smoke and warns residents of a possible fire. Some CO detectors also have an integrated LCD display. It provides information about the current CO concentration in the room air. Detectors with a built-in memory function also allow the highest measured CO values since the last reset to be called up. The self-test function of the detector is of great importance. By pressing a button on the CO detector, you can check whether the device is working correctly and whether the alarm is triggered correctly. This function provides security and gives the good feeling that the detector will function reliably in an emergency.

In large houses and apartments, it may be advisable to install networked CO detectors. These detectors work in combination and together give an alarm if the CO concentration rises somewhere in the house. This can be useful, for example, if a CO detector is installed in a locked cellar room and triggers an alarm. The warning tone may not be heard on the upper floors. If a second, networked detector is installed on the upper floor, it also sounds the alarm and can warn the residents of the danger.
