AELAB AQMS-450 Carbon Dioxide Analyzer – Precision CO₂ Monitoring System

The AELAB AQMS-450 Carbon Dioxide Analyzer is a precision instrument engineered for real-time CO₂ quantification in ambient and industrial air environments. Utilizing Gas Filter Correlation Non-Dispersive Infrared (GFC-NDIR) detection, it ensures highly accurate, low-drift, and interference-free performance for applications in environmental monitoring, HVAC validation, and industrial air safety compliance.

⚙ Design & Construction

The AQMS-450 features a white cavity optical chamber combined with an anti-corrosion surface treatment for long-term operational stability. An integrated CO₂ purging device minimizes ambient gas interference, while the precision optical path and signal filtering enhance sensitivity and reduce background noise. Its modular design supports easy maintenance, and the compact rack-mounted form factor enables installation in laboratory benches or mobile monitoring stations.

🔬 Working Principle / Testing Method

The AELAB AQMS-450 operates on the GFC-NDIR principle, where infrared radiation passes through a gas filter correlation wheel that alternates between CO₂-absorbing and non-absorbing paths. The difference in detected light intensity corresponds to the CO₂ concentration in the sample gas. This method effectively eliminates cross-sensitivity to other gases, providing precise and repeatable results even in variable environmental conditions. Temperature and pressure are continuously compensated by the onboard processor to maintain measurement integrity.
