CO2 Meters – What Are They and How Do They Work?

Until recently, carbon dioxide monitoring was not something most organisations had given much thought to. However, with the recent pandemic and all of the other changes in workplace practices such as face masks and social distancing CO2 monitoring has been brought to the forefront.

What is CO2 emission measurement device?

Co2 meter detect the level of carbon dioxide in a given space by monitoring breathing activity. They are useful for ensuring a safe working environment where there is poor ventilation. CO2 levels can rise dangerously quickly in such environments which are why it is vital to use a high quality monitor.

The most common type of CO2 detector uses non-dispersive infrared (NDIR) sensors that are designed to measure the concentration of CO2 within an air sample. Different gases have different molecular structures that absorb infrared energy at different wavelengths – this is how the sensor can tell if there is CO2 present. The NDIR sensor then converts this into a usable reading via a microprocessor and the display will reflect the CO2 levels within a space.

There are also electrochemical CO2 detectors that work by measuring electrical current to determine the amount of CO2 present in an air sample. This is done by exposing the surface of the sensor to CO2 which reacts with it to produce an electrical charge that can then be measured.

There are a range of CO2 monitoring solutions on the market with different features and prices. For example, Air Guardian is a state of the art monitor that combines design with functionality at an affordable cost. The device provides real time information on CO2 levels in a room and will alert you when it exceeds recommended values. This will help you to activate your ventilation system so that the room can be renewed and avoid any risk of CO2 build up.
