The non-dispersive infrared market size is expected to advance at a CAGR of 7.4% during 2022–2030, to reach USD 956 million by 2030. This is ascribed to the growing demand for monitoring the air quality and GHG emissions.
Moreover, in healthcare settings, this technique is used for the monitoring of the CO2 concentration in human respiratory gases, in order to detect lung malfunction.
The growing wastewater treatment demand is also propelling the market growth. In municipal wastewater treatment plants and onsite wastewater treatment systems, NDIR sensors are used to track nitrite, nitrate, and ammonia levels. According to government articles, approximately 45 rivers in India are severely polluted, and their pollution levels need to be monitored at regular intervals. This is due to the increasing population and urbanization in the country, which lead to the generation of huge wastewater volumes.
NDIR is also used to measure the levels of ethylene released during the process of fruit ripening. Even in harsh environments, it provides reliable measurements. Moreover, with its long-term stability, minimal cross sensitivities, and high selectivity, NDIR allows for precise control over the fruit ripening process.
The focus on the safety of workers is increasing across industries. Workers in the mining, fertilizers, chemicals, medical, industrial & manufacturing, and oil & gas industries are exposed to extremely hazardous environments. Various toxic gases, such as carbon monoxide, carbon dioxide, and sulfur hexafluoride, are generated during various extraction and refining processes in the oil & gas and chemical industries. If inhaled in excess, they can have severe effects on human health, even leading to death in extreme cases. High concentrations of harmful and combustible gases in the workplace environment can even cause explosions or fire accidents.
Technological advancements are positively impacting the market, with various players focusing on the development of technologically advanced NDIR solutions. For instance, in February 2022, Oizom launched AQBOT, which offers improved and accurate data and high-speed monitoring of the air quality. Moreover, it is easy to install and lightweight. For protection from harsh weather, the sensor module is enclosed in an IP65 rugged composite enclosure.
In addition, in May 2020, the new high-speed SprintIR-R CO2 sensor with a 50Hz measurement rate was launched by GSS. The main applications of this product are in healthcare, sports sciences, and food packaging. The product uses the solid-state LED optical technology to respond quickly to changing CO2 concentration.
Europe is expected to show significant share during the forecast period, due to the implementation of stringent regulations with regard to the emission of greenhouse gases and the rising focus on monitoring the concentration of toxic gases. In November 2022, the EU presented Euro 7 emission standards to increase the use of electric vehicles, in order to deliver effective air quality improvements. The rules are known for the deployment of zero-emission vehicles. For implementing this, the NDIR can be used for the monitoring of emissions.
The most-significant non-dispersive infrared market players are Honeywell International Inc., N.E.T. Srl, NevadaNano, S+S Regeltechnik GmbH, MIPEX TECHNOLOGY, Senseair AB, Emerson Electric Co., and Acal BFi group.
