High-Precision CO2 Sensor Developed from Cubic Mature NDIR Technology Platform

The Core Key to the Development of Cubic High Precision CO2 Sensor

In the pursuit of optimized indoor air quality (IAQ) and energy efficiency, the latest standard of ASHRAE 62.1 has underscored the necessity of employing high-precision CO2 sensor for Demand Control Ventilation with the accuracy requirement of ±75ppm at 600, 1000 &2500ppm. Presently, Non-Dispersive Infrared (NDIR) technology stands out as the optimal solution to meet the stringent precision requirement.

Leveraging two decades of dedicated research and development, Cubic, a leading manufacturer of smart gas sensors and superior gas analyzers, has cultivated exceptional expertise in NDIR technology and has established a gas sensing technology platform based on NDIR technology to provide innovative CO2 sensors, which is ideal for the DCV systems and stands at the forefront of Cubic technological innovation.

Built upon a mature NDIR technology platform and the fundamental principles of NDIR technology, Cubic self-developed NDIR CO2 sensor is fully compliant with ASHRAE 62.1 precision requirement by precisely designing the light source, filters, and optical path, enabling high accuracy of ±75ppm at 600, 1000 &2500ppm, across a wide temperature and measurement range. At the same time, Cubic NDIR CO2 sensors exhibit high selectivity to accurately measure CO2 concentrations without interference by other gases. Additionally, selecting a strict component for Cubic NDIR CO2 sensor guarantees a 15-year lifespan. Based on Cubic’s auto-zero-calibration mechanism, Cubic NDIR CO2 sensor can autonomously maintain accuracy across its entire lifetime without frequent manual calibration.

Conclusively, Cubic mature core gas sensing technology platform based on NDIR technology provides CO2 sensors with the advantages of high accuracy, long lifespan, auto-zero-calibration mechanism, and continuous monitoring capability, making Cubic NDIR CO2 sensors widely used in DCV systems to realize meticulous control to improve indoor air quality and energy efficiency in buildings.
