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.

Aethlabs microAeth® Model AE51是一种高敏感性及便於随身携带的仪器，利用光学量测气胶微粒对光的吸收，以定量”黑碳” (BC)成分。仪器参照Aethalometer侦测原理，此原理的量测应用已经有30年，世界上超过1000部仪器。

AE51 抽取空气样品的流速介於50到150 mL/min之间，通过3 mm直径的过滤滤片，微粒沈积在采样点上，由一稳定的880奈米LED光源和二极管探测器来测量。 该采样点的吸光度(光的衰减，ATN)，由一个参考点「Reference」与采样点「Sensing」的相对测量结果，使用已知的每单位质量的「Black Carbon」物质吸收效率，再转换成BC质量浓度的表示单位，奈克每立方米(ng/m3) 来估算黑碳浓度。

仪器的操作参数由一个应用软体(microAethCOM)设定，并由USB接线上载到AE51。仪器启动之后，操作部分是完全自动化。操作时，微处理器进行光学测量，量测并稳定空气流量，计算BC质量浓度并且记录数据於内部固定的记忆体。数据经过一段时间后可由同一个软体下载。

AE51从内部可再充电电池获得它的能量。同一USB接线可提供电池充电，可选择由USB插座连接外部电脑或用变压器充电。单一电池情况下，根据操作的配置，仪器将可操作6到24个小时。

The microCyclone is a miniature PM_2.5 size-selective inlet for the microAeth.

This sharp-cut cyclone has a size cut of 2.5 micron at 50 mlpm
and 1.6 micron at 100 mlpm.
