A side stream EtCO2 sensor, accurate and durable, suitable for various complex environments. Compatible with multiple protocols. Plug and play, no zero calibration required. Stable and durable.
There is no circuit inside the host, just a serial port.
Temperature pressure compensation, timing and self-calibration functions, full-range calibration, to ensure accurate measurement within the range of 0-20%
The gas circuit, hardware and software are carefully designed to ensure the long-term stability of the module
Suitable for battery-powered use, automatic pressure compensation. Maintain measurement accuracy in an extremely wide air pressure range of 400-960mmHg.
The Filters can work continuously for a long time, and can be reused, reducing the user's cost.
Intelligent identification and light indication of filter insertion and breathing status.
Multiple communication protocols, and more than 20 years of accumulated technology and experience, easily help you achieve technical and practical improvements

High signal-to-noise ratio
Capno-S is a side stream 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
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;
