Aethlabs MA350 - Automated Outdoor Black Carbon Monitor

The microAeth® MA350 is a real-time 5-wavelength UV-IR Black Carbon monitor housed in an outdoor-rated case with an 85 sampling location automatic filter tape advance system which allows for 3-12 months of continuous measurements.

The device is a self-contained instrument with built-in pump, flow control, data storage, and 4X the battery capacity of the MA200. The MA350 also features onboard GPS, satellite time synchronization, accelerometer, altimeter/barometer, and sensors for relative humidity and temperature. Wireless communications are provided for network or smartphone app integration and connection to other wireless health and environmental sensors. A BLDC brushless pump is optional.

The MA350 is designed as a network node to be installed outdoors on street poles and along fence lines for extended multi-month measurement campaigns with low maintenance and infrequent site visits. The 85 location filter tape cartridge allows for long term continuous sampling of higher concentrations for up to a year depending on the sampling environment conditions and instrument settings.

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.

Measurement method Real-time, 5 wavelength spectrum analysis by measuring the rate of change of transmitted light due to continuous particle deposition on flter. Measurement at 880 nm interpreted as concentration of Black Carbon (‘BC’). Measurement at 375 nm interpreted as Ultraviolet Particulate Matter (‘UVPM’) indicative of woodsmoke, tobacco, and biomass burning.

Measurement wavelengths 880 nm, 625 nm, 528 nm, 470 nm, 375 nm

DualSpot® Loading Compensation Real-time analysis by measuring the rate of change in absorption of transmitted light due to the continuous collection of aerosol on flter. Simultaneous collection on two spots in parallel at different fow rates.
