Non-dispersive Infrared (NDIR) market size was valued at US$ 690.1 Million in 2025, expanding at a CAGR of 7.7% from 2026 to 2033.
A non-dispersive infrared (NDIR) sensor is defined as the simplest spectroscopic sensor, which can be considered a gas detector. NDIR sensors can be used for gas analysis, which can identify and analyze the concentration of different kinds of gases, including carbon dioxide, hydrocarbons, and carbon monoxide. The sensor analyzes the type of gas through the measurement of the infrared absorption in the specific wavelength.
Some of the main types of gases that are considered for the Non-dispersive Infrared (NDIR) market include carbon dioxide, hydrocarbons, carbon monoxide, and others. Carbon dioxide sensors are used in measuring the quantity of infrared radiation absorbed by the molecules of carbon dioxide. In addition, CO2 sensors on the basis of non-dispersive infrared (NDIR) technology are used in automobiles to measure the concentration of CO2 in the automotive exhaust. These applications are driving continued demand for NDIR sensors across diverse industries and gas-monitoring requirements.
Non-dispersive Infrared (NDIR) Market- Market Dynamics
Increasing Need For Air Quality Control To Drive Market Demand
The growing need for monitoring the quality of the air both indoors and in industry and in the environment has created a growing need for monitoring the concentrations of such gases as CO2, CO, and CH4 using non-dispersive infrared (NDIR) sensors. In April 2025, according to the article by NIH.gov, air pollution remains one of the significant factors affecting human health. According to WHO estimates, about 4.2 million deaths of people around the world occur due to ambient air pollution each year. In Japan, within the SORA project, the health condition of 10,069 schoolchildren aged 6-9 years was observed during four years. The results were that 309 children (3.1%) suffered from asthma, and there was a 7% increase in the incidence of asthma in relation to 0.1 µg/m3 of mean elemental carbon concentration. Also, in Japan, the PM2.5 air-quality standard is <=15 µg/m3 per year and <=35 µg/m3 per 24 hours, which underlines the necessity of monitoring the air quality. These trends highlight the growing need for NDIR sensors to support accurate and continuous air-quality monitoring.
In terms of gas type, carbon dioxide (CO2) holds a key position in the Non-dispersive Infrared (NDIR) market due to the use of NDIR CO2 sensors in ensuring precise and reliable gas measurements for application in HVAC, ventilation, industrial safety, and environment sectors. For instance, in April 2025, according to the UK government, carbon dioxide (CO2) was nearly 78% of the net territorial greenhouse gas (GHG) emissions in the UK, and the total GHG emissions in the UK were about 367 MtCO2e. This is further estimated to drive the demand for accurate co-monitoring and detection systems.
Non-dispersive Infrared (NDIR) Market- Geographical Insights
The Asia-Pacific markets are seeing the use of NDIR sensor-based ventilation and indoor air quality monitoring solutions being fuelled by building efficiency and the growing need for automated HVAC control systems. For instance, in April 2025, according to the Government of India, energy efficiency programs for key sectors, including buildings and appliances, will lead to a reduction in energy consumption of about 89 million tonnes of oil equivalent (Mtoe) by 2030 compared to the case without them. To help implement the building efficiency programs in India, the Bureau of Energy Efficiency (BEE) has introduced the Energy Conservation and Sustainable Building Code (ECSBC) for commercial buildings and the Eco Niwas Samhita (ENS) implemented by state governments and local governments. Additionally, air conditioners, ceiling fans, and refrigerators have been made compulsory to comply with the standards and labelling programme with a rating of appliances between 1 and 5 stars, where 5 stars is the most efficient appliance category. These initiatives are expected to accelerate demand for NDIR sensors in smart building and HVAC applications.
South Korea Non-dispersive Infrared (NDIR) market - Country Insights
South Korea's strong industrialisation and urbanisation, together with growing environmental awareness in South Korea, are increasing demands for various industries and technologies. For instance, in June 2025, according to the OECD, there is a growing concern about the environment in South Korea, given the fact that the share of energy industries and manufacturing in the emission of greenhouse gases exceeds 50%, and the GHG emissions in South Korea are above the level of GHG emissions in the OECD average. Moreover, renewables provided less than 3% of the total energy supply, while only 16% of the energy demand in Korea was covered by domestically produced energy, which demonstrates a heavy dependence of South Korea on imported fossil fuels. These factors are accelerating South Korea's transition toward cleaner energy, sustainable technologies, and low-carbon industrial solutions.
The Non-dispersive Infrared (NDIR) market is characterised by intensifying competition between traditional sensor makers with their extensive application knowledge and new technology innovators who are looking at ways to create inexpensive, small-sized, and reliable NDIR sensors. Companies like E+E Elektronik, smartGAS Mikrosensorik GmbH, SST Sensing, Figaro Engineering Inc., and MEMBRAPOR AG are making their mark with their innovations in infrared detection techniques, multi-gas sensors, miniaturisation, and applications. In May 2025, smartGAS launched its new FLOWEVO PLUS NDIR sensor to detect sulphur dioxide (SO2F2) using a dual beam/reference channel technique. These advancements are intensifying competition and accelerating innovation across the NDIR sensor market.
In May 2026, MSA Safety made an announcement regarding an agreement to purchase Autronica Fire and Security, a company offering fire and gas detection solutions. This deal was aimed at enhancing MSA Safety's fixed gas detection and broadening its range of safety solutions.
