摘　　要：探讨了光电比色多元素分析仪的计量特性和校准方法,确定了校准项目和技术指标。在含量不大于1.0%时含量示值误差的绝对值不大于0.05%,含量大于1.0%时含量相对示值误差的绝对值不大于5%;重复性:不大于5%;线性系数:大于0.99。用该拟定校准方法对光电比色多元素分析仪的计量校准结果进行分析,结果表明该方法可行。The metrology performance and calibration method for photoelectric colorimetric multi-element analyzer were discussed, the calibration items and technical indexes were determined. The main technical indicators of photoelectric colorimetric multi-element analyzer, when the content indication is not more than 1.0%, the absolute value of the error is not more than 0.05%, when the content indication is more than 1.0%, the absolute value of relative error of content indication is not more than 5%. The repeatability is not more than 5%, linear coefficient is greater than 0.99. The calibration results of the photoelectric colorimetric multi-element analyzer are statistically analyzed by the proposed calibration method. The results show that the method is feasible.
