A mainstream end-tidal carbon dioxide monitoring sensor, it has a unique sample cell protects internal NDIR components from pollution. Compatible with multiple protocols (Respironics, Phasein, CPT, KM, etc.)
There is no circuit inside the host, just a serial port.
Carefully selected multi-channel narrowband filters and infrared light sources, hardware design and software algorithm, to achieve high signal-to-noise ratio, to ensure the measurement accuracy in the temperature range of 5-50°C and the concentration range of 0-20%.
Suitable for battery-powered use, instant start, accurate data can be obtained within 10 seconds of power-on.
By receiving the pressure and interfering gas parameters input by the host, the compensation calculation can be automatically performed to ensure the measurement accuracy in a variety of occasions.
Reliable EtCO2 OEM solutions, multiple communication protocols to make your products quickly upgrade assembly.
