氯离子快速测定仪仪器示值误差不确定度评定

Evaluation of Uncertainty of Instrument Indication Error for Chloride Ion Rapid Measuring Instrument

氯离子快速测定仪是建筑材料生产和建筑检测领域经常使用的一种离子选择性电化学仪器,目前尚未有统一的国家检定规程或者校准规范,我们参考JTJ 270-98《水运工程混凝土试验规程》和JGJT 322-2013《混凝土中氯离子含量检测规程》对该类仪器进行量值溯源并对仪器示值误差测量不确定度评定,为该类仪器校准方法的研究提供了参考。

The rapid chloride ion analyzer is a kind of ion selective electrochemical instrument which is often used in the field of building material production and building detection.At present,there is no unified national verification regulation or calibration standard.We refer to JTJ 270-98"Testing Code of Concrete for Port and Waterwog Engineering"and JGJT 322-2013"Technical specification for test of Chloride ion content in Concrete"Calibrate this kind of instrument and evaluates the uncertainty of indication error,which provides a reference for the research of calibration methods of instrument.
