The MicroFLOW CO2 .5000 ppm sensor is suitable for a wide range of demanding applications that require precision and reliability.


With a measurement range of up to 5000 ppm (parts per million), NDIR gas detection remains an extremely accurate method for detecting carbon dioxide in a very wide range of applications in almost all industries. A few examples of these applications are described in more detail in the following sections.

Industry: For industrial process monitoring, the 5000 ppm range provides accurate resolution. This is important for applications where minimal fluctuations in CO2 concentration are critical, such as chemical reactions. In addition, NDIR gas analysis in this range allows for more precise control of production processes or applications where even the smallest CO2 emissions can affect product quality. In industrial food processing, this range can be used for more specific needs, such as packaging process control or canned food quality assurance, where lower CO2 concentrations are important. In the controlled ripening of fruit or the production of beverages, finely tuned carbon dioxide monitoring is essential to ensure product quality and shelf life.

Biotechnology: Precise measurement of CO2 concentrations in microorganism cultivation, cell culture or fermentation is often required in biotechnology applications. Accurate monitoring enables optimal control of environmental conditions, which in turn can affect the yield and quality of biotech products. The extended measuring range of up to 5000 ppm allows finer gradation and therefore more precise control of these processes.

Medical: In medical technology, NDIR gas measurement is used, for example, in respiratory gas analysis. It enables the precise determination of CO2 concentrations in the inhaled and exhaled air of patients. This data is important for the diagnosis and monitoring of respiratory diseases and for patient monitoring. The extended measurement range enables more precise monitoring, especially in critical medical environments.

Agriculture: In agriculture, the measurement range of up to 5000 ppm enables more precise monitoring of CO2 concentrations in greenhouses or targeted control of plant growth to ensure optimal environmental conditions. Fine tuning of CO2 concentrations directly affects plant growth and photosynthetic efficiency, which has a positive effect on yield and quality.

Mobility: In the development of low-emission vehicles, the monitoring of emission control systems, or traffic monitoring, it is important to record lower CO2 levels to obtain more accurate data. The analysis allows a more detailed assessment of the environmental impact or air quality and the derivation of appropriate measures to improve air quality.



Our NDIR gas sensor provides precise measurements for monitoring and controlling carbon dioxide. The maximum deviation of measured gas concentrations within the entire measuring range of up to 5000 ppm is less than one percent, thanks to 10-point linearization.

The sensor detects even minimal gas concentrations, facilitating identification of minimal changes in the gas mixture. You can choose your desired measuring range for your application (e.g. 500 ppm) from the entire measuring range (0 to 5000 ppm).

The µP.sens pressure sensor located in the cuvette block compensates for deviations in measurement results caused by pressure value fluctuations or barometric changes (< 0.1 % / 10 hPa). The system is designed to prevent both leaks and falsification of measured values. By integrating the pressure sensor into the cuvette block, the module requires less space than comparable sensors.

Each module is guaranteed to be temperature compensated. In the climate chamber, each sensor is tested and calibrated by recording and correcting the error curve during measurement with a test gas at a specified concentration. The sensor is tested and corrected at the zero and full scale points, as well as at other typical temperatures within the sensor's operating range of 5 - 45 °C. The maximum deviation of the measurement result is therefore less than 1 % per 10K.



The most commonly used industrial interfaces RS232 and CAN bus are available ex works. When ordering, you can select an interface for your individual presetting. If required, you can easily change the interface later using the MARS light software. Please follow the instructions in the software manual.

The cuvette is optimized for carbon dioxide and the specified concentration of the measuring range up to 5000 ppm.

Our sensor allows measurements in a wide pressure range of 300 - 1200 hPa. This provides customers with a wider range of applications compared to conventional sensors, such as applications in higher geographical locations or systems operating at negative pressure.



The gas connection blocks are made of anodized aluminum with high chemical resistance for long life and reliability in demanding conditions. Stainless steel gas connections provide additional durability.

Climatic chamber testing prevents premature failure of components in the temperature application range.



The MARS light software, specifically developed for our gas sensors, can be downloaded for free. This enables immediate use for initial measurements of your gas sensor and saves time in the project as there is no need to develop your own testing software. The sensor requires less than 1 watt of input power, making it suitable for use in battery-operated devices. The voltage range of 9-30 volts allows for easy integration into most existing systems.

Sometimes, gases may require pre-cooling or heating before the analysis. By monitoring the temperature of the gas in the measuring system, potential condensation effects in the cell can be prevented.

Cleaning and maintenance can be done with ease thanks to the modular design, unlike many similar products.

The manual contains all necessary information on set-up and operation.
