Application fields of NDIR gas measurement

Which gases are measurable by NDIR analysis?



The measurement of gas concentrations to ensure and monitor process stability is of central importance in all industrial processes involving gases. The exact and reproducible detection of the gas concentration is an essential component of important applications, especially in medical and environmental technology. In addition, the NDIR (non dispersive infrared) gas analysis allows either the broadband or highly selective detection of hazardous substances in private or industrial areas such as the monitoring and detection of explosive gases and pollutants. It is an optical analysis tool for measuring the concentration of such gases. With respect to the optical interaction with infrared active gases, the NDIR analysis is a fast and efficient process.

Infrared spectroscopy has emerged as very precise and long-term stable method for the detection of IR-active substances in NDIR gas and fluid analysis. The measurement systems long-term stability is based on infrared components.

Based on different functional principles and our component portfolio, we combine the optimum gas sensor solution for your measurement task. You can order individual product samples from our product finder or contact our NDIR gas analysis experts directly.
