Air Pollution Gas Monitors Air Pollution Gas Monitors are devices used to detect and measure the concentration of harmful gases in the atmosphere to ensure environmental safety and regulatory compliance. Typical gases include: Sulfur Dioxide (SO‚) Nitrogen Dioxide (NO‚‚) Carbon Monoxide (CO) Ozone (O) Volatile Organic Compounds (VOCs) Carbon Dioxide (CO‚) These monitors are used in Urban air quality monitoring stations Industrial areas (factories, power plants) Construction sites Traffic-heavy zones Indoor air quality assessments Research and environmental studies Sensors are used in these monitors are Electrochemical Sensors (for CO, NO‚, SO‚) Non-Dispersive Infrared (NDIR) Sensors (for CO) Photoionization Detectors (PIDs) for VOCs Laser Scattering Sensors (for PM) Accuracy varies by model and sensor type. Regulatory-grade monitors offer high precision (+/-5%), while low-cost sensors may have +/-10% accuracy. Calibration greatly affects accuracy.
