Carbon Dioxide Measurement Amplifier
Part #: CO2100C

The CO2100C is an infrared-based carbon dioxide measurement module designed to provide accurate measurement of the carbon dioxide content in ambient air, expired breath, and in breathing gas mixtures.

The CO2100C is calibrated to measure carbon dioxide in the range 0 to 10%.  The module provides a selectable range of analog outputs that map voltages to 0-10% carbon dioxide concentration levels.

The module is a lightweight, rugged unit that offers a number of advanced features, such as fast response and user-adjustable sampling flow rate.

Sampling line connections for input and output flow are readily accessible on the front panel of the module.

  • The CO2100C module interfaces (via the AFT20 gas sampling interface kit) with the AFT15A and AFT15B mixing chambers, the AFT21 and AFT22 non-rebreathing T valves or the AFT25 mask with integral non-rebreathing T valve.

The excellent linearity of the CO2100C makes it possible to calibrate the module by checking two optimally separated points in the desired measurement range.

Details

Compatibility


The CO2100C module is equipped with a variable speed pump to adjust the flow over a wide range of sampling conditions.

The CO2100C module records quickly varying carbon dioxide concentration levels. This fast-response analyzer is ideal for monitoring time-averaged CO2 levels using mixing chambers or real-time CO2 levels for breath-by-breath measurements.

The module is equipped with a variable speed pump to adjust the flow over a wide range of sampling conditions. The module uses a single beam infrared, single wavelength measurement technique.

The CO2100C module measurement is based upon the single beam, single wavelength technique (SBSW), where wavelength selection is implemented via a carefully specified narrow-band optical filter. The speed of response is obtained by generating a fast infrared carrier signal, which is attenuated by the infrared absorption of carbon dioxide present, and a detection system that converts fast changes of this attenuation into an electrical output.

The CO2100C offers a stable and inherently linear measurement of carbon dioxide.
