A particulate monitor measures airborne dust and fine particle concentrations, categorized by size fractions such as PM2.5 and PM10, to quantify air contamination levels. These devices help assess whether air filtration systems effectively capture harmful particles and protect indoor air quality.
Technical Measurement Standards
Particulate monitors measure particles in micrometers (µm), with PM2.5 representing particles 2.5 microns or smaller and PM10 for particles up to 10 microns. EPA and WHO guidelines set safe PM2.5 levels at 12 micrograms per cubic meter (24-hour average). Professional monitors use optical or gravimetric methods to determine concentrations with accuracy typically within 10-15% of reference standards.
HVAC Diagnostics
Technicians use particulate monitors to test filter performance, detect leaks in ductwork, and evaluate whether upgraded filtration improves air quality. Real-time readings show the immediate impact of filter changes or system adjustments.
Compliance and Health
Particulate data supports IAQ documentation and helps facility managers meet indoor air standards. Elevated PM2.5 levels justify HEPA filter installation or increased filter change frequency to protect occupant respiratory health.
