【摘要】 总结了省级实验室pH(酸度)计计量比对的结果,用归一化偏差(E_n值)法对比对结果进行评价,并对造成En值偏离的原因进行技术分析,对pH(酸度)计校准过程给出建议,为计量技术机构开展pH(酸度)计的计量检定或校准提供参考。更多还原

【Abstract】 The results of measurement comparison of pH meters from the provincial laboratories were summarized in this paper and evaluated via normalized error(E_n) method; meanwhile, technological analysis was made on the reasons causing E_n error. In addition, some suggestions were presented for pH calibration, providing reference for the metrological technical institutions in the metrological verification or calibration of pH meter.更多还原
