【摘要】 PM_2.5作为灰霾的主要成分,是衡量空气质量优劣的一个重要指标,是环境空气质量监测领域必测的六个监测因子之一。做好PM_2.5监测仪的日常运行管理及维护,保证仪器监测数据准确,事关为环境管理部门提供决策数据的科学性,显得尤为重要。美国热电（Thermo Fisher）PM_2.5监测仪作为一款主要品牌的PM_2.5监测仪器,在国内已有广泛的应用,在国内已安装的PM_2.5监测仪中占相当比重,本研究通过对该品牌的5030-SHARP型PM_2.5监测仪器日常维护、常见故障及处理进行分析,以期为PM_2.5监测仪运维技术人员提供一定的技术参考。更多还原

【Abstract】 As the main component of haze,PM_2.5 is an important index to measure the quality of air,and it is one of the six monitoring factors in the field of environmental air quality monitoring.It is particularly important to manage and maintain the daily operation of PM_2.5 monitor to ensure the accuracy of monitoring data,which is related to the scientificity of decision-making data for environmental management departments.PM_2.5 monitor of Thermo Fisher in American,as a major brand of PM_2.5 monitor,has been widely used in China and accounts for a considerable proportion of the installed PM_2.5 monitor in China.In order to provide some technical reference for the operation and maintenance technicians of PM_2.5 monitoring instrument,this study analyzed the daily maintenance,common faults and treatment of the 5030-SHARP PM_2.5 monitoring instrument of Thermo Fisher in American.更多还原
