A growing number of CO alarms now have a display which gives you the sensor’s current reading on CO particulates in the air, though – to save batteries – you will only see this after a test or if the reading goes above safe levels. Whether you choose a battery-powered carbon monoxide alarm, a plug-in model, or a hardwired CO alarm, install a detector on each level of your home and near any potential sources of CO gas, such as furnaces, water heaters, or fireplaces. The digital display shows carbon monoxide readings that are taken every 15 seconds, indicating any changes in CO levels. Powered by two replaceable alkaline batteries, the 5DCO takes CO readings every 15 seconds and, from 30ppm, will display the current CO level on its LCD screen.

Carbon monoxide sensors have a finite lifespan of between five and seven years, although a few manufacturers now claim that their sensors will last a full ten years.

This is arguably safer, and recent Scottish laws require that homeowners and landlords either fit tamper-proof alarms with a long-life Lithium battery or a mains-wired CO alarm if there’s a carbon-fuelled appliance – such as a boiler, woodburner or open fire – on the property. The only thing to watch out for is that it’s powered by a pair of AA batteries which need replacing roughly every two years We had no issues whatsoever during tests, but it means this alarm won’t be compliant with the new Scottish regulations. If your property has an attached garage with a connecting door through to the house, it is recommended to fit a CO alarm inside the house leading from that doorway.
