The microAeth® MA300 is a small, real-time 5-wavelength UV-IR Black Carbon monitor with an 85 sampling location automatic filter tape advance system which allows for 3-12 months of continuous measurements.

• Real-time 5-wavelength UV-IR spectrum measurement (880, 625, 528, 470, and 375 nm) for Black Carbon and UVPM source insight
• 85 sampling location filter tape cartridge enabling 3-12 months of continuous measurement
• DualSpot® loading compensation method corrects for optical loading effects
• Self-contained with built-in pump, closed-loop flow control, and 4X the battery capacity of the MA200
• Onboard GPS, satellite time synchronization, accelerometer, altimeter/barometer, and humidity/temperature sensors
• Wi-Fi and Bluetooth Low Energy wireless plus USB connectivity to cross-platform microAeth® Manager software

General

Parameter	Specification
Measurement method	Real-time, 5 wavelength spectrum analysis by measuring the rate of change of transmitted light due to continuous particle deposition on filter. 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 filter. Simultaneous collection on two spots in parallel at different flow rates.
Timebases	1, 5, 10, 30, 60, 120, or 300 seconds
Flow Rates	Internal pump provides 50, 100, 150, or 200 ml/min
Pump Options	Standard internal diaphragm pump. Optional internal rotary vane pump
Flow Control	Internal mass flowmeters with closed-loop control
Filter Material	Polytetrafluoroethylene (PTFE)
Filter Capacity	MA300 Filter Tape Cartridge with PTFE material (85 sampling locations)
Sensors	Accelerometer, Relative Humidity, Temperature, Altimeter/Barometer
