Measurement Principle

Non-dispersive infrared technology measures selective CO₂ optical absorption. Drift compensation, baseline calibration, interface scaling, physical configuration and model-specific precision are not identical across the Cubic CO₂ portfolio.

AirAlign engineering note: Do not extrapolate the manufacturer’s ±(30 ppm + 3%) accuracy statement across the entire 10,000 ppm UART/I²C range. The model-specific source conditions the statement on an ABC operating period and on humidity. The original technical table and notes take precedence over a generic model-family marketing heading.

Applications

CO₂ monitoring in OEM HVAC devices, ventilation systems, environmental sensing, agriculture and related manufacturer-specified applications. High concentration or safety-critical use requires the corresponding model and a validated complete instrument.
