摘要
采用扩散管动态配气装置发生甲醛标准气体,对BH-1型甲醛快速分析仪的各项性能指标(响应时间,稳定性)进行了测试,确定了分析条件(温度,相对湿度,风速)对仪器的影响,结果显示快速分析仪测定甲醛气体浓度的相对误差小于10%。研究表明经定期校准的甲醛快速分析仪用于室内甲醛气体污染的检测可获得可靠的结果。
Using standard formaldehyde gas with diffuse tube dynamic equipment, the authors test performance of BH-1 fast formaldehyde analyzer including response time and stability, then, found out cicrumstance influence to the analyzer, such as temperature, relative humidity, wind speed. The relative error of detection is below 10%. The analyzers with periodic calibration can determine indoor formaldehyde reliably.
