Air Quality Monitoring
Air Quality Monitoring measures low concentrations of pollutants that affect health and comfort (ppm, ppb or µg/m³ levels, below flammable ranges) in indoor and outdoor work environments. The category includes VOC monitors, particulate matter monitors (PM2.5/PM10), CO/CO2 monitors, and integrated Indoor Air Quality (IAQ) systems. It differs from gas detection by focusing on chronic exposure indicators rather than immediate hazards.

About this category
Air quality monitoring differs from industrial gas detection by focusing on long-term health, productivity, and occupant satisfaction. VOC monitors watch volatile compounds from paints, furniture, and building materials using PID or MOS technology — they are used in offices and schools for VOC monitoring at ppb levels. Particulate monitors measure PM2.5 (under 2.5 microns, deep lung penetration) and PM10 (under 10 microns, upper airways) using laser light scattering. CO2 monitors are essential in enclosed environments because concentrations above 1000 ppm signal insufficient ventilation and may be associated with drowsiness and headache. CO monitors here differ from industrial-safety CO sensors by operating at lower ranges (typically 0-50 ppm) for indoor environments. Integrated IAQ systems combine several sensors (VOC, PM, CO2, temperature, humidity) in one unit with a display and a cloud platform; IAQ systems vary in the number of built-in sensors and the level of BMS integration for smart buildings — used in modern schools, hospitals, and offices. Relevant reference guidance includes ASHRAE 62.1 and the WELL Building Standard.
