CO2 Mainstream Module Capno-M

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.)


Features of CO2 Mainstream Module Capno-M

Plug and play

There is no circuit inside the host, just a serial port.

High Precision

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%.

Low Power Consumption

Suitable for battery-powered use, instant start, accurate data can be obtained within 10 seconds of power-on.

Atmospheric pressure and Interference gas compensation

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.

OEM Solution

Reliable EtCO2 OEM solutions, multiple communication protocols to make your products quickly upgrade assembly.
