Carbon Dioxide MeterCarbon Dioxide Meter

At a base level a carbon dioxide meter for rising levels of CO2 in air and activates audible or visual alarms if it detects dangerously high CO2 concentrations. Some models have the ability to trigger relays or third party systems such as ventilation, fire panels or building management/security systems if they detect a CO2 leak. They can also monitor for a range of other gases as well as temperature, humidity and air pressure to provide a comprehensive solution for monitoring indoor climatic conditions in workplaces, rooms or vessels.

The best and most accurate carbon dioxide detectors use NDIR technology (Non-Dispersive Infra-Red) to measure gas concentrations. These sensors have an LED source emitting infra-red light at one end and a special filter which only detects carbon dioxide at the other. When the LED source and the detector are switched on CO2 diffuses through the filters and is detected. The amount of detected gas is proportional to the intensity of the infra-red light emitted by the sensor.

Measuring CO2 Levels: The Functionality of Carbon Dioxide Meters

In general, it is a good idea to monitor a room for excessive levels of CO2 as these can make people feel drowsy and may even impair cognitive performance. Some common rooms that are likely to be used for a long period of time like offices, breweries or pubs should have a monitor installed to reduce the risk of occupants suffering from CO2 poisoning. Other areas such as rooms where CO2 has been extinguished using fire hoses should have a monitor in place to ensure adequate cross-ventilation is achieved prior to entering as high levels of CO2 could be life threatening.
