摘　　要：目前Andersen采样器是国际通用的测定空气细菌和真菌粒子浓度的标准仪器,闭环控制可以获得可调节的稳定气流,实现了基于稳定气流下的全自动两级安德森采样器,其轻巧、便携、操作方便、可远程控制。并通过与标准采样器的对比实验(t检验统计分析),对全自动采样器的性能以及采样效果进行验证,采样效果满足需求。Currently,Andersen sampler is the international general standard instrument for measuring air concentration of bacterial and fungal particles. The adjustable and steady air flow is controlled by the closed-loop. The automatic two-stage Anderson sampler is achieved based on the stability of air flow. It is lightweight,portable,easy to operate and can be remotely controlled. Through the contrast experiment with the standard sampler( t-test statistical analysis),we test the sampling efficiency and validity of the automatic sampler,and the sampling effect meets the demand.
