The top 5 best CO2 monitors on Ventilationland.co.uk
Do you know how healthy the air in your home or workspace actually is? If you spend long periods of time in a particular room, it's worth knowing whether the air quality is good. If it isn't, you may experience various health complaints, such as headaches or difficulty concentrating. Especially when you're in the same room with several people, the CO2 level can rise quickly. A CO2 level that's too high isn't just harmful in itself; viruses also spread more easily in a room with a high ppm value. A CO2 meter has therefore become indispensable! This device shows straight away when the CO2 level rises too high, and so when it's time to ventilate a bit more.

Which CO2 meter should I choose?
When choosing a user-friendly CO2 meter, a number of factors play a role. Pay particular attention to the points below.
Calibration option
As a sensor gets older, “drift” can occur: a slight deviation in the measurement. Choose a meter with automatic self-calibration (ABC), so calibration by the manufacturer isn't needed.
Measuring range
Ideally, choose a CO2 meter with a measuring range of at least 5,000 ppm. That way, you'll still get a reliable reading even at a high concentration, for example in a full meeting room.
Margin of error
Every CO2 monitor has a margin of error. A maximum deviation of 10% for a reading up to 2,000 ppm, or 100 ppm for a value up to 5,000 ppm, is considered acceptable for reliable use.
Display and colour indicator
Choose a meter that shows the measured value on a display. A colour indicator or alarm, also known as a traffic-light function, shows you at a glance when it's time to ventilate.
Data logging
Data logging can be useful for everyone: it lets you see how CO2 levels change throughout the day, and the effect of, for example, opening a window or door.
