CO2 Gas Detector List

A comprehensive list of CO2 Gas Detector options. CO2 (Carbon Dioxide) is a gas contained within normal air and is essential for life on Earth. However, in higher concentrations it can become detrimental to health. The following gas detectors are used to alert unsafe levels which can occur in enclosed spaces within industries such as breweries and beverage production.

What is a CO2 Gas Detector and Why Use It?

While CO2 (Carbon Dioxide) is a normal component of the air you breath, it can cause problems at higher concentration. The average level within normal outside air is is around 350 to 450 ppm (parts per million). CO2 starts to become a problem above 600 ppm with varying degrees of health complications. Early symptoms of high levels can be drowsiness, difficulty breathing, muscle fatigue and at levels as high as 100,000 ppm a person could pass out and asphyxiate causing death.

A CO2 Gas Detector is therefore essential within industries that use or produce Co2. Typically the greatest danger is a gradual build up within enclosed spaces. Suitable ventilation is always integrated into planning these industries, and CO2 Gas Detection is used to ensure the ventilation is keeping levels safe.

Another potential danger is below ground storage and cellars. There is a possibility, in certain conditions that CO2 could accumulate at lower levels, if air exchange and ventilation is poor. CO2 is slightly more dense (heavier) than Oxygen and Nitrogen.

Portable CO2 Gas Detector

Portable gas detectors are lightweight wearable instruments designed to alert individual workers of dangerous gas levels as they perform their every day duties. Typically plant maintenance workers are required to use personal portable detectors as they are more likely to enter enclosed areas.

Which is the best type of CO2 Gas Sensor?

CO2 can be detected by electrochemical sensors (EC), Metal Oxide Semiconductor Sensors (MOS) and Infrared (IR) sensors. The most effective option for longevity and to avoid false readings is IR sensors, specifically Single path Non-dispersive Infrared (NDIR) as used in the D12Ex-IR listed on this page. NDIR sensors are not effected by drift which can be a problem with EC and MOS sensors.
