HTabsOverviewThe microAeth® MA200 is a compact, real-time, wearable 5-wavelength UV-IR Black Carbon monitor with a 15 sampling location automatic filter tape advance system which allows for up to 2-3 weeks of continuous measurements. The device is a self-contained instrument with built-in pump, flow control, data storage, and battery with onboard GPS, satellite time synchronization, accelerometer, altimeter/barometer, and sensors for relative humidity and temperature. Wireless communications via Wi-Fi and Bluetooth Low Energy are provided for network and/or smartphone app integration and connection to other wireless health and environmental sensors. The MA200 is designed for on-person, mobile applications and multi-day / multi-week measurement campaigns with low-power operation. The spectrum measurement provides insight into the composition of light absorbing carbonaceous particles and helps to distinguish among the different optical signatures of various combustion sources such as diesel, woodsmoke, biomass, and tobacco. The instrument supports the DualSpot® loading compensation method which corrects for optical loading effects and provides additional information about aerosol optical properties.

SpecificationMeasurement Parameter: Black CarbonSpecification: Product name MA200 - Portable Black Carbon Monitor Manufacturer Aethlabs Description Real-time 5 wavelength UV-IR analysis by measuring the rate of change in absorption of transmitted light due to continuous collection of aerosol deposit on filter (employs DualSpot® Loading Compensation technology). Measurement at 880 nm interpreted as concentration of Black Carbon. Measurement at 375 nm interpreted as Ultraviolet Particulate Matter (‘UVPM’) indicative of woodsmoke, tobacco, and biomass burning. Data storage capacity for multiple years of continuous measurement, battery life dependent on run parameters (sample rate, analysis timebase).
