CO2 Mainstream Module Capno-M+

An original patented product that can be used for both intubated patients and non-intubated patients, breaking through the limitation that mainstream modules can only be used for intubated patients.


Features of CO2 Mainstream Module Capno-M+

Patented Products

With its compact design and two kinds of adapters, the mainstream module can be used for intubated patients and non-intubated patients. Breathing light intuitively and qualitatively reacts to real-time concentration.

High Precision

Careful selection of infrared devices, hardware design and software algorithm, to achieve high signal-to-noise ratio and ensure the measurement accuracy within the temperature range of -5-50°C and the measurement range of 0-20%.

Suitable For Adults, Children and Newborns

Excellent performance and low cost. Plug and play, the host does not need internal circuit, but just a serial port. The data can be measured within 4 seconds after power on. 

Automatic Pressure Compensation

There is an atmospheric pressure sensor inside, which is suitable for various altitude ranges. Built in interference gas compensation algorithm.

Reliable Carbon Dioxide OEM Solutions

A variety of protocols, so that your products quickly upgrade assembly.
