摘　　要：随着人们环保意识的不断提升,空气中污染物浓度的测量受到越来越多人的关注,数显式大气采样器也因其读数较为方便等特点,成为目前应用最为广泛的空气采样设备。但现行有效的JJG956—2013《大气采样器检定规程》,只适应于采用转子流量计控制气体流量式大气采样器的检定。本文从采样原理出发,从转子流量计式大气采样器和数显式大气采样器气体流量控制方式不同入手,研究和探讨数显式大气采样器检定过程,分析不同显示流量示值误差计算的方法,进一步保证采样和大气监测工作的准确可靠,以期望对大气环境监测和环境评价工作提供技术支持。With the continuous improvement of people’s awareness of environmental protection,more and more people pay attention to the measurement of pollutant concentration in the air,and the digital air sampler has become the most widely used air sampling equipment because of its convenient reading and other characteristics.However,the current effective JJG 956-2013,Verification Regulation of Air Samplers,is only suitable for the verification of gasflow control air sampler with rotameter.Based on the sampling principle and the different gasflow control methods of the rotameter air sampler and the digital air sampler,this paper studies and discusses the verification process of the digital air sampler,analyzes the error calculation methods of different displayflow values,and further ensures the accuracy and reliability of sampling and atmospheric monitoring,in order to provide technical support for atmospheric environment monitoring and environmental assessment。
