Mainstream EtCO2 Capnography 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 Mainstream EtCO2 Capnography 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.

Mainstream Capnography Sensor Capno-M Application Scenarios

  • High signal-to-noise ratio

Capno-M is a mainstream CO2 module.

It is equipped with high-quality Multi-Channel Narrowband Filters, IR Light Source, Well-designed Hardware Circuit and Software Algorithms to achieve gas concentration measurement with high signal-to-noise ratio;

  • Long continuous working time

With the self-developed adapters, they can continuously work for a long time in high temperature environment.

  • Plug-and-play

It can be used in conjunction with a multi-parameter monitor. The monitor only needs one interface, which can be connected to the module for use.

  • Atmospheric pressure compensation

There is an internal atmospheric pressure sensor, which can automatically adjust the atmospheric pressure and suitable for various altitude ranges and harsh environments;

  • OEM solutions

We provide the reliable carbon dioxide OEM solutions, with multiple protocols, so that products can be quickly upgraded and assembled.
