Cubic NDIR CO2 Sensor in Compliance with ASHRAE 62.1-2022

Explore Cubic NDIR High Accuracy Sensor

To improve energy efficiency in buildings, the latest published ASHRAE 62.1-2022 proposes measures to enhance building energy efficiency, notably raising CO2 measurement standards to ±75 ppm at 600, 1000, and 2500 ppm concentrations as the following shows,

6.2.6.1.3.4 CO2 sensors shall be certified by the manufacturer to be accurate within ±75 ppm at concentrations of 600, 1000, and 2500 ppm when measured at sea level at 77°F (25°C). Sensors shall be factory calibrated and certified by the manufacturer to require calibration not more frequently than once every five years. Upon detection of sensor failure, the system shall provide a signal that resets the ventilation system to supply the required minimum quantity of outdoor air (Vbz) to the breathing zone for the design zone population (Pz).

Under this context, to realize high-accuracy feature of CO2 sensors for ventilation systems becomes very critical.

In the basis of more than 20 years’ R&D accumulation and dedication, Cubic has established a gas sensing technology platform based on NDIR technology and developed NDIR CO2 sensors that can realize highly accurate measurement, fully compliant with ASHRAE precise measurement of ±75 ppm at concentrations of 600, 1000, and 2500 ppm. Cubic NDIR CO2 sensors also have advantages of long lifespan, auto-zero-calibration mechanism, and continuous monitoring capability to better realize meticulous control to improve indoor air quality and energy efficiency.

Simultaneously, complemented by a robust and reliable supply chain, Cubic capitalizes on the virtuous synergy of technological innovation, supply chain management, and lean production practices to effectively meet customers' burgeoning demands and provide holistic gas sensing solutions.

With 20 years of expertise in NDIR technology, Cubic, will pay continuous attention to policy shifts in ASHRAE Standards to provide qualified and reliable solutions to customers worldwide. Cubic will also devote its best efforts to the ventilation systems and HVAC application for more influential technological innovations.
