MA300 Multi band Micro Black Carbon Analyzer

Instrument Introduction:

microAeth^®The MA300 multi band micro black carbon meter is a compact, real-time measurement, handheld ultraviolet infrared five band micro black carbon meter. There is an automatic replacement system for the sampling filter belt inside.

The instrument is equipped with a built-in pump, flow control, data storage, battery GPS、 Satellite automatic timing, accelerometer, altimeter, barometer, and temperature and humidity sensors. Provide Wi Fi and low-power Bluetooth wireless communication.

Spectral measurement provides light absorption information of different carbon containing particle components, which helps distinguish different combustion sources such as diesel and biomass combustion. Support the use of dual point compensation method to correct overload effects.

Technical parameters:

Measurement method: Five band light absorption: The absorbed particles measured at 880nm are defined as "black carbon" (BC), and the absorbed particles measured at 375nm are defined as "ultraviolet particles" (UVPM);

Measurement bands: 880 nm, 625 nm, 528 nm, 470 nm, 375 nm;

Data correction: Dual point overload compensation algorithm: Synchronize data collection with different flow rates at two points and measure the changes in optical attenuation at the points in real time. Compensate and correct the overload effect through the algorithm to make the measurement more accurate;
