Market Breakup by End Use
Market Breakup by Region
Outdoor monitors hold the largest share in the global air quality monitoring system market, as they are designed to measure and analyse pollutants found in the ambient air of outdoor environments
Outdoor monitors utilize cutting-edge sensors and technologies to identify various pollutants. Strategically positioned in urban, industrial, and residential areas, they offer real-time air quality data.
Indoor monitors notify occupants and building managers about pollution levels, facilitating prompt interventions. Indoor air pollution poses significant health risks to residents in the short and long term.
Chemical pollutants dominate the global air quality monitoring system market, primarily due to their diverse range of harmful substances emitted into the atmosphere from human activities, industrial processes, and natural sources
Chemical pollutants, such as volatile organic compounds (VOCs), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), and other harmful gases, are critical considerations for public health and environmental impact. Specialized sensors and analytical methods are employed in advanced monitoring technologies to accurately quantify these pollutants.
Biological contaminants, including bacteria, viruses, animal dander, cat saliva, house dust, mites, cockroaches, and pollen, originate from various sources. Managing indoor humidity levels helps minimize the growth of certain biological pollutants.
Active or continuous monitoring holds the largest segment of the global air quality monitoring system market share due to its utilization of specialized equipment and sensors for the continuous collection of real-time air quality data.
Active or continuous monitoring systems operate continuously, offering constant updates on pollutants. They deliver a thorough insight into pollutant levels, fluctuations, and patterns, particularly valuable in swiftly changing pollution dynamics of urban and industrial zones.
Stack monitoring systems are utilised to detect and measure harmful gases emitted into the atmosphere from stacks, chimneys, and DG units.
