15.2 X 35.6 X 25.4 cm Portable Ambient Air Particulate Monitor, 5 Kg

This Air Particulate Monitor is a highly sensitive and accurate portable monitor for ambient and environmental monitoring. Interchangeable size-selective sampling heads for PM10, PM2.5, PM1.0 and TSP enables specific particle fractions to be targeted. The human respiratory system is divided into three regions where particles of certain sizes or aerodynamic diameter are likely to be deposited. Both the United States EPA (Environmental Protection Agency) and OSHA (Occupational Safety and Health Admin- istration) set strict guidelines and methods for these different particle sizes. Particulate Matter (PM) is becoming an in- creasing concern and making current news headlines due to its adverse link to human respiratory health and environmental danger. These lung damaging particles called aerosols, are found everywhere; inside commercial and residential buildings, industrial work places and the outside ambient environment. This is an innovative light scattering nephelometer and filter gravimetric air sampler combined in one portable compact and lightweight design. The unique design allows the air quality investigator to collect size se- lective particulate matter using two proven techniques: light scattering and filter gravimetric. Size selective sampling is achieved by a single jet impactor for PM-10, PM-2.5, PM-1.0um, TSP, or 4.5um with OSHA approved respirable cyclone.
