NDIR gas sensor for CO2 measurement in incubators MicroSENS Hightemp IR CO2 sensor

NDIR gas sensors

We develop high-quality and trend-setting gas sensor modules for measuring and monitoring gas concentrations. Thus, infrared active gases in industry and medical technology, as well as environmental and laboratory technology, can be reliably detected by NDIR analysis from ppm to percent.

With more than 20 years of experience in the development and production of IR components, Micro-Hybrid is one of the world's leading manufacturers of high-quality measuring systems. Our NDIR gas sensors convince through design and user-friendliness. We also offer customer and maintenance services such as calibration service and equipment.



Reliable and highly accurate measurement results

by the use of high-quality IR components and packaging technologies made by Micro-Hybrid as well as our unique engineering know-how

Specially designed for harsh environments

Our HermeSEAL technologies enable gas sensors to be offered for use in harsh environments. High temperatures up to 190° C and difficult environmental conditions are no obstacle for our sensors.

Our high-quality standards for components and processes guarantee stability and a long service life.

Innovative and flexible

Continuous further development of all components and parts with a focus on long-term stability and harsh environmental conditions, multi-gas solutions and many years of experience make us your OEM partner for the development of gas sensors.

NDIR gas sensors product overview

MicroSENS - Sensors for diffusion-based measurement applications

MicroSENS High temp ir carbon dioxide sensor


  • Open cuvette
  • For absorption distances up to 50 mm
  • Sample directly in the atmosphere to be measured

MicroFLOW - Gas sensors for analysis applications

MicroFLOW IR methane sensor

Gas monitoring and measurement applications

For process control, environmental measurement and laboratory analysis, over 100 different gases (technical gases such as propane, methane or carbon dioxide etc., refrigerants, anaesthetic gases, liquids such as oil etc.) can be reliably detected from ppm to the percentage range using NDIR analysis. This method has numerous applications in industry and laboratory technology.


Monitoring the gas concentration in fruit ripening sites and greenhouses
Monitoring the concentration of relevant gases, such as CO2 or ethylene, enables optimal conditions in fruit ripening warehouses and greenhouses.

Process monitoring

Gas analysis for process monitoring and leakage location in industry
Effective and reliable measurement of industrial exhaust gases, process gases such as methane, propane, carbon monoxide and carbon dioxide or alcohol and biogas

Cell incubators

Gas analysis for monitoring the CO2 concentration in cell incubators
