近年来大颗粒物污染日趋严重，准确监测颗粒物PM2.5迫在眉睫。目前国外监测仪器已在国际上普遍使用，国内真正的知识产权产品比较少，产品的精度以及稳定性也有待提高。采用基于β射线法原理研制了PM2.5质量浓度在线监测系统，在仪器结构中提出采用原位检测的方法，并进行与标准称重法的比对实验来验证系统的可行性，结果表明两者测量数据的相关性为0.988。通过数据校正补偿后与监控站赛默飞仪器比对实时监测数据，日测量数据平均值相对偏差仅为1.8％。

Particulate air pollution has become increasingly serious in recent years,accurate monitoring particulate matter PM2.5 is imminent. Currently,with abroad monitoring instrument used in the world,domestic real intellectual property products are relatively few and the precision and stability of the products also need to improve. In this arti￣cle,PM2.5 mass concentration on￣line monitoring instrument was developed based on the beta ray method. The situ detection in the instrument structure was proposed and was conducting with the standard weighing method of compare experiment to verify the system. The results showed that the correlation of both measurement data was 0.988. After da￣ta correction of compensation and alignment,conducting with monitoring station real￣time monitoring data of the ther￣moinstrument,the average relative deviation of measurement data was only 1.8%.
