Besides improving ventilation rates and reducing energy costs, CO2 monitors can help identify and alert you to leaks early – before they displace enough oxygen to trigger O2 alarms. They are especially useful in living rooms, schools, offices, and public facilities.

Carbon dioxide detector also known as capnography, is used in hospitals to monitor patients during procedural sedation and for diagnosing sleep issues like apnea and hypoventilation. The devices display the waveform of expired CO2 and patient data on a screen, giving health care professionals a real-time picture of a patient’s breathing status. They are also used to detect deteriorating breathing, as CO2 levels will fall before pulse oximetry can catch it.

Breath of Fresh Air: The Importance of Carbon Dioxide Monitors in Indoor Environments

A good CO2 monitor is a simple, yet accurate device that uses an NDIR sensor to measure carbon dioxide concentrations. It has a battery, is portable, and allows for manual calibration. Some can record data over long periods of time and are available with an app for easy monitoring, control, and analysis.

When looking for a carbon dioxide detector, you should consider your needs and budget. Some monitors are more advanced than others and include additional sensors, such as relative humidity and temperature. While these are not necessarily essential, they can give you a more complete view of the air quality in your home or business. For example, the Aranet4 monitor is one of the most popular CO2 detectors on the market due to its incredibly long battery life, a built-in app, and over-the-air updates. Its price is slightly higher than other models, but it’s a great choice if you need a portable, accurate CO2 detector.
