Cubic TDLAS O₂ & NDIR CO₂ Dual-Gas Sensor
Gasboard-2513Gasboard-2513

Gasboard-2513 is an O2/CO2 dual gas sensor developed for medical respiratory applications, utilizing TDLAS technology for oxygen measurement and NDIR technology for carbon dioxide measurement within a single sensor module. It delivers ultra-high selectivity, strong resistance to cross-gas and humidity interference, and a fast response time of <200 ms, supporting real-time monitoring under rapidly changing respiratory conditions.
Gasboard-2513 features calibration-free and maintenance-free operation, superior vibration resistance, and long-term measurement stability, ensuring reliable performance across different clinical and operating environments.
With a compact modular design, ultra-low power consumption, and standard digital interfaces, Gasboard-2513 can be easily integrated into ventilators, anesthesia machines, metabolic analyzers, and CPET systems, enabling simultaneous and stable O2 and CO2 monitoring for both steady-state and dynamic respiratory measurements.
