主要特征

SILENT符合PM取样的要求，旨在对家庭环境中收集的粉尘进行化学表征：

非常低的噪音（35db），允许PM收集在卧室，教室，医院，博物馆，图书馆等;

在Æ47mm膜过滤器上收集PM，可进行后续化学分析;

PM2.5或PM10采样入口也可以收集粗粒（> 2.5mm或> 10mm）;

流速：10升/分钟，能够确保收集足够的PM量，用于室内环境中PM浓度和成分的日常测量。

 为了确保延长无人值守的采样周期，可以在顺序单元中安装多达4个进样口（每个进样口带有一个薄膜过滤器），并按所需顺序对循环进行编程。

MAIN CHARACTERICTICS

SILENT Sequential Air Sampler  is a sequential instrument specifically developed for particulate matter collection in indoor environment. 

SILENT meets the requirements of PM sampling aimed to the chemical characterization of the collected dust in domestic environments:

very low noise (35db), allowing PM collection also in bedrooms, classrooms, hospitals, museums, libraries, etc.;

PM collection on Æ 47mm  membrane filters, allowing subsequent chemical analyses;

PM2.5 or PM10 sampling inlet      with the possibility to collect also the coarse fraction (>2.5mm or >10mm);

flow rate: 10 l/min, able to assure the collection of a sufficient PM amount for the daily measurement of PM concentration and composition in indoor environments.

 To assure extended unattended sampling periods, up to 4 inlets (each one carrying one membrane filter) can be installed in the sequential unit and programmed for cycles in the desired sequence.
