Do I Use An O2 or CO2 Monitor?

Making The Right Choice Can Help Save A Life!

Commercial gases like carbon dioxide (CO2), nitrogen (N2) and oxygen (O2) are often used in various combinations in hospitality environments including bars, restaurants and pubs or recreational facilities like stadiums, indoor arenas and swimming pools. 

Carbon dioxide is a tasteless, odorless gas. While small amounts of CO2 are considered harmless, as levels of the gas increases, the negative effects on humans quickly begin to be present. Exposure to even a small amount of CO2 in an enclosed space can result in nausea, dizziness, headaches, while a more prolonged exposure can lead to confusion, convulsions and ultimately loss of consciousness.

If you are using or have CO2 stored in your facility, it is critical to have a dedicated carbon dioxide monitor installed to measure toxic gas levels and provide warning alarms in the event of a leak. 

Should a CO2 leak occur, the gas will quickly start to replace breathable O2 in a work area. The normal percentage of O2 in the air that we breathe is approximately 21 percent. Studies have shown the displacement rate at which CO2 replaces the O2 content can cause symptoms from just a small decrease beginning at 19.5 percent.  

Oxygen monitors are designed to measure the O2 content in a work environment exclusively. The monitors typically sound an alarm when the sensor records an O2 content change of 5 percent. However, that five percent CO2 change will only result in a one percent drop in O2 readings. 

The CO2 levels increase faster than the O2 levels being monitored. As a result, the CO2 buildup will cause negative reactions that can lead to sickness and unconsciousness before an O2 monitor can sound the alarm and alert anyone to a dangerous CO2 buildup. 

Scientific engineers with the Analox Group regularly study current gas monitoring trends and solutions. These gas analytical experts are quick to point out that it’s important in any environment where gasses are being used or stored to use the right tool for the right application.

The Analox Group has a wide range of CO2 monitoring solutions.  Among the most popular gas analyzing devices are the AX60+, the ACG+, Apsida and CO2 Buddy
