The rising rate of urbanization is expected to drive the growth of the Non-Dispersive Infrared (NDIR) market going forward. Urbanization refers to the process in which an increasing share of the population moves from rural areas to cities, resulting in the expansion of urban centers and the development of infrastructure. Economic opportunities fuel this shift, as people migrate to cities seeking better jobs, higher incomes, and improved living standards, contributing to the growth of urban areas. Non-Dispersive Infrared (NDIR) sensors support urbanization by providing accurate air quality monitoring in expanding cities, helping manage pollution levels, and ensuring healthier living environments for growing urban populations. For example, in February 2024, according to the United Nations Organization, a US-based international organization, about 58% of the global population lived in urban areas in 2024, with projections indicating this share will rise to 60% by 2030 and could exceed 68% by 2050. Therefore, increasing urbanization is driving the growth of the Non-Dispersive Infrared (NDIR) market.

Key players in the non-dispersive infrared (NDIR) market are concentrating on advanced solutions, including high-sensitivity detection, to support industrial companies in meeting new EU regulations on methane emissions. This focus contributes to environmental sustainability and the reduction of greenhouse gases. High-sensitivity detection arises from NDIR sensors' ability to accurately measure low concentrations of target gases by detecting specific infrared absorption wavelengths without using dispersive elements, facilitating precise gas concentration analysis. For instance, in May 2024, ABB Ltd., a Switzerland-based engineering firm, unveiled OA-ICOS technology designed to assist industrial companies in adhering to the forthcoming EU Methane Regulation. This technology offers sensitivity more than 1,000 times greater than traditional methods and detects leaks 10 times faster than conventional equipment, enabling the accurate location, attribution, and quantification of gas leak sources. This innovation is crucial as it enables industrial companies to identify and prioritize essential repairs, ensuring compliance with strict EU regulations on methane emissions and supporting global efforts to mitigate greenhouse gases.

In May 2023, smartGAS Mikrosensorik GmbH, a Germany-based manufacturer of high-precision NDIR gas sensors and analyzers used in various industrial applications, merged with Shanghai Industrial Gas Analytical Systems Co., Ltd. (SIGAS) for an undisclosed amount. Through this merger, the two companies aim to optimize their upstream and downstream industrial chains. SIGAS is a China-based company involved in industrial gas analysis equipment and provides comprehensive gas monitoring systems.

A non-dispersive infrared (NDIR) sensor is a spectroscopic sensor commonly employed as a gas detector. It is utilized in gas analysis to assess the concentration of gases like carbon dioxide, hydrocarbons, and carbon monoxide. The sensor operates by detecting the type of gas through measuring the amount of absorbed infrared at the required frequency.

The primary types of gases involved in the non-dispersive infrared (NDIR) market include carbon dioxide, hydrocarbons, carbon monoxide, and others. For instance, a carbon dioxide sensor monitors the infrared (IR) radiation absorbed by carbon dioxide molecules to determine gaseous carbon dioxide levels.
