摘要
文章介绍了便携式甲醛分析仪的应用及电化学甲醛分析仪检测原理,对电化学甲醛分析仪分析方法进行评价,其方法的重复性≤5.5%,示值误差≤10.0%,线性相关系数r=0.9991,测量结果的相对扩展不确定度Uγ=13.6%(k=2),表明电化学甲醛分析仪能够满足空气中甲醛检测方法的要求。
In the thesis, we introduce the apply of portable formaldehyde gas analyzer and its inspecting principle; evaluate the method of portable formaldehyde gas analyzer. The repeatability is less than or equal to 5.5 %, the error is less than or equal to10.0 %, the linearity correlation coefficient is equal to 0.9991, the extended uncertainty evaluation of measurement is equal to Uγ=13.6% k=2）. It shows that the apply of portable formaldehyde gas analyzer can meet the requirements of formaldehyde gas test.
