What are the general ranges of carbon dioxide concentration in the monitored environment?

The range of carbon dioxide (CO2) concentrations in monitored environments can vary depending on the specific context. Here are some common situations and their associated CO2 concentration ranges:

 

Indoor Air Quality Monitoring:

Normal Conditions: Typically, indoor air maintains CO2 concentrations between approximately 400 to 600 parts per million (ppm).
Elevated Concentrations: In poorly ventilated indoor spaces, CO2 concentrations may rise above 1000 ppm.

Office and Commercial Buildings:

Standard Range: CO2 levels in indoor offices and commercial buildings are generally maintained within the range of 400 to 1000 ppm, but factors such as ventilation, occupancy, and other variables may cause fluctuations.

Greenhouses and Agricultural Applications:

Optimizing Growth Conditions: Greenhouses may monitor CO2 concentrations to optimize plant growth conditions, with levels potentially exceeding 1000 ppm and even higher.

Industrial Process Monitoring:

Process-Dependent: In certain industrial processes, elevated CO2 concentrations may be generated or monitored, such as in brewing, food processing, and chemical production.

HVAC and Ventilation System Monitoring:

Ventilation Control: Monitoring CO2 levels indoors helps adjust ventilation systems to ensure good indoor air quality.

Life Science Laboratories:

Experimental Conditions: Some life science experiments require monitoring and control of CO2 concentrations in laboratories to simulate specific physiological conditions.

These are just examples, and actual CO2 concentration ranges will depend on the particular application. When selecting the range for a CO2 monitoring device, it is advisable to consider the typical CO2 concentrations in the specific application environment.
