摘　　要：:采用扩散管法动态配气系统发生甲醛标准气 ,对便携式甲醛分析仪的各项性能指标进行了测试 ,同时与国家标准检验方法 (GB/ T16 12 9)进行了现场对比。结果表明 :与国家标准检验方法相比较 ,该仪器的总不确定度为 7%。The performance of portable formaldehyde analyzer was tested by a standard formaldehyde gas generation system, the gas was generated by diffusion tube. The evaluation included testing the zero, calibrating the drift, response times and the accuracy of the analyzer, and testing the effect of relative humidity. In compare with the standard method (AHMT method GB/T16129) testing in the fields, the overall relative uncertainty of the formaldehyde analyzer was 7%.
