Application Scenarios of CO2 Sidestream Module Capno-S+

  • High signal-to-noise ratio

Capno-S+ is a side stream CO2 module, 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

For side stream modules, there are built-in long-life sampling pumps, ensuring a one-way flow of exhaled air; and high-quality filter that can work for a long time even 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.
