Air Quality Monitoring Instrumentation
Particulate Matter (PM)
Ambient particulate has become the primary interest of air quality specialists and government regulators. Particulate matter (PM) concentrations are commonly categorized by size: PM2.5, PM10 or TSP (total suspended particulate). In some instances, other aerosol fractions may be of interest (e.g. PM4.0, PM1.0 or ultrafines).
PM monitoring instrumentation is used to determine the mass concentration. Additional analysis of the collected aerosol will provide the chemical make up of the particles, which may include metals, ions and elemental substances.
There are two methods of determining PM concentrations:
Continuous Monitors - which are capable of providing data in real or near-real time.
Manual Samplers - which aspirate and deposit PM on collection media for subsequent gravimetric or chemical analysis.
Met One BAM-1020
The BAM-1020 is a continuous, U.S. EPA Federal Equivalent Method (FEM) monitoring system that is approved for PM2.5 and PM10 measurements. As a result of its reliability and precision, it is the most widely used PM2.5 FEM on the market.
Met One BAM-1022
The BAM-1022 is the only EPA approved continuous PM2.5 monitoring method that conducts measurement at near ambient conditions. This helps eliminate artifacts caused by gradients in sample temperature and humidity. The BAM-1022 is a fit for purpose monitoring system designed for outdoor deployment. The BAM-1022 provides both hourly and short term concentration results.
E-Series Ambient Particulate Monitor
The E-Series is a custom built forward light-scattering dust monitor specifically designed for portability and remote deployments. The built in microprocessor logs all data and has the ability to notify operators of high PM readings (as well as other alarm conditions) via email and SMS. A built in web server facilitates data retrieval. It is well suited for perimeter monitoring, and for applications that require prompt mitigation to elevated PM levels.
The built-in microprocessor has sufficient power to accommodate additional sensors. The E-Series is now available with up to four metal oxide semiconductor or PID sensors for the measurement of NO2, O3, CO and VOCs.
The PQ100 is a manual U.S. EPA Federal Reference Method (FRM) for the determination of PM10. Its compact size and low power consumption (12VDC) make it the ideal sampler for quick deployments and use in remote areas where line power is not available.
The PQ200 is a manual U.S. EPA Federal Reference Method (FRM) for the determination of PM2.5 or PM10. Its compact size and low power consumption make it the ideal sampler for quick deployments and use in remote areas.
Met One BC-1054
Black Carbon (BC) is a constituent of PM that is commonly produced by incomplete combustion. BC measurements are useful in PM source identification, and climate change studies. The BC-1054 is a continuous monitoring system operating throughout the infrared and ultraviolet spectral regions. It offers improved traceability compared to traditional filter-based optical techniques through its unique factory calibration process.
