一、概述1.测量依据JJG535-2004《氧化锆氧分析器检定规程》。2.环境条件温度为0~40℃,相对湿度:≤85%。3.测量标准氮中氧标准气体,其相对扩展不确定度为Urel=2.0%,k=2。4.被测对象氧化锆氧分析器,最大允许误差为±5%FS。5.测量过程通入一定浓度的氮中氧标准气体,平衡后读取被测氧化锆氧分析器的示值,重复测量3次,3次的算术平均值与标准气体实际值的差值,即为氧化锆氧分析 First, an overview 1. Measurement based on JJG535-2004 “zirconia oxygen analyzer test procedures.” 2. Environmental conditions Temperature 0 ~ 40 ℃, relative humidity: ≤ 85%. 3. Measurement standard nitrogen oxygen standard gas, the relative expansion uncertainty Urel = 2.0%, k = 2.4. The measured object zirconia oxygen analyzer, the maximum allowable error of ± 5% FS. 5. The measurement process of access to a certain concentration of nitrogen in the oxygen standard gas, after reading the measured oxide zirconia analyzer showed the value of repeated measurements 3 times, 3 times the arithmetic mean and standard gas actual value of the difference, Zirconia is oxygen analysis
