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是一種高敏感性及便於隨身攜帶的儀器，利用光學量測氣膠微粒對光的吸收，以定量”黑碳” (BC)成分。儀器參照Aethalometer偵測原理，此原理的量測應用已經有30年，世界上超過1000部儀器。

AE51 抽取空氣樣品的流速介於50到150 mL/min之間，通過3 mm直徑的過濾濾片，微粒沈積在採樣點上，由一穩定的880奈米LED光源和二極管探測器來測量。 該採樣點的吸光度(光的衰減，ATN)，由一個參考點「Reference」與採樣點「Sensing」的相對測量結果，使用已知的每單位質量的「Black Carbon」物質吸收效率，再轉換成BC質量濃度的表示單位，奈克每立方米(ng/m3) 來估算黑碳濃度。

儀器的操作參數由一個應用軟體(microAethCOM)設定，並由USB接線上載到AE51。儀器啟動之後，操作部分是完全自動化。操作時，微處理器進行光學測量，量測並穩定空氣流量，計算BC質量濃度並且記錄數據於內部固定的記憶體。數據經過一段時間後可由同一個軟體下載。

AE51從內部可再充電電池獲得它的能量。同一USB接線可提供電池充電，可選擇由USB插座連接外部電腦或用變壓器充電。單一電池情況下，根據操作的配置，儀器將可操作6到24個小時。

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.
