The 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. The device is a self-contained instrument with built-in pump, flow control, data storage, and battery with onboard GPS, accelerometer, satellite time synchronization and other sensors. Wireless communications are provided for network or smartphone app integration and connection to other wireless health and environmental sensors. It is designed for on-person, mobile applications and multi-day measurement campaigns with automatic filter tape advance and 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, biomass, and tobacco. The instrument supports DualSpot® loading compensation method which corrects for optical loading effects and provides additional information about aerosol optical properties.
