It is invisible, odorless, and tasteless: Carbon monoxide (CO) is a dangerous respiratory poison that is produced during the incomplete combustion of carbon-containing materials. What helps here: buying a CO detector. A carbon monoxide alarm like the Ei208D from Ei Electronics provides the only effective protection against potentially fatal CO poisoning. This detector, designed for a lifespan of 10 years, checks the CO levels in the surrounding air every 4 seconds and reliably warns as soon as there is a danger. The use of such a CO detector is particularly sensible in places where combustion appliances such as fireplaces, pellet heaters, briquette heaters, oil heaters, gas boilers, gas heaters, or instantaneous water heaters are used. The battery-operated Ei208D is designed as a CO alarm for flexible installation in living spaces and can also be used in recreational vehicles such as motorhomes, caravans, or boats. If the electrochemical sensor of the Ei208D detects elevated CO levels, the integrated LCD display of the alarm provides specific instructions on how to best respond to the danger.
