Santacary iP2 is a high precise instrument mainly used to measure the fine particles PM2.5 using the laser technology. iP2 can continuously display the ambient concentration of fine particles in micrograms per cubic meter of air (µg/m3). Fine particles PM2.5 refers to fine particulate matter in ambient air aerodynamic equivalent diameter less than or equal to 2.5 micron particles. It was suspended for a long time in the air, the higher its content concentration in the air, the more serious air pollution. Outdoor fine particles PM2.5 primarily come from car, truck, bus and off-road vehicle exhausts, the burning of fuels such as wood, heating oil or coal and natural sources such as forest and grass fires. Indoor fine particles PM2.5 come from tobacco smoke, cooking, burning candles, and operating fireplaces and fuel-burning space heaters. Studies suggest that long term exposure to fine particulate matter may be associated with increased rates of chronic bronchitis, reduced lung function and increased mortality from lung cancer and heart disease. iP2 PM2.5 Meter can be widely used in the car, burning plants, petrochemical facilities, thermal power plants, restaurants, hospitals, mining facilities, metal refineries, commercial and public buildings, and other confined spaces for personal health. THEORY OF OPERATION This PM2.5 meter uses a laser scattering theory to obtain the number of particles in the equivalent particle size and volume units of different size through the algorithms based on MIE theory.
