Air quality monitoring systems are utilized for repeated measurement of ‘air pollutants’ or ‘criteria air pollutants’. The contaminated air contains harmful contaminants that are responsible for various health issues.  They identify different pollutants such as particulate matter, sulfur dioxide, Volatile Organic Compounds (VOC), carbon monoxide, and nitrous oxide. Air pollution monitoring and controlling data are crucial for assessing air pollution and environmental pollution policies by national and local authorities, public and private companies, and national organizations.

• In Europe, the Ambient Air Quality Directive (2008/50/EC) enforces strict pollutant limits and requires member states to maintain extensive monitoring networks and publicly report air quality data. Similarly, in India, the National Clean Air Programme (NCAP) aims to reduce particulate pollution by 20–30% by 2024 (extended beyond) across more than 130 non-attainment cities, significantly boosting the deployment of Continuous Ambient Air Quality Monitoring Stations (CAAQMS).

The market is expected to witness significant growth owing increasing demand for improving air quality, which has led to growing demand in the market. Rising global pollution levels and government air quality mandates across the globe also propel the market growth.

HORIBA, Ltd. is one of the prominent players in the market. The company is a manufacturer and distributor of environmental measuring instruments, automotive emission measurement systems, and a wide range of scientific analyzers.
