Ma350; Gps; Timebase; Wi-Fi - Aethlabs microAeth MA200 Operating Manual

9.3. MA350

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, or 300 seconds
