光浊度计结合β射线法颗粒物监测仪安装维护浅析

Discussion of installation and maintenance on the particulate monitor based on light scattering and beta attenuation

PM2.5是指大气中空气动力学直径小于或等于2.5微米的颗粒物,它对人体健康和环境空气质量的影响极大。广州市环境监测中心站将美国赛默飞世尔公司的5030SHARP光浊度计结合β射线法颗粒物监测仪应用于细颗粒物PM2.5监测。经过一段时间的使用及维护,目前该5030SHARP监测仪运行稳定。本文着重介绍5030SHARP监测仪的安装,以及维护中容易出现的问题,并提出一些使用注意事项,分享仪器维护经验,希望以此为环境监测技术人员提供该仪器安装和维护方面的参考,以获得准确的监测数据。

This paper focuses on the installation of 5030 SHARP and the problems that may appear in daily maintenance ,and presents the points for attention in daily use.
