滴定原理土壤有机质分析仪的校准方法

Calibration of permanganate index analyzers

通过研究滴定原理土壤有机质分析仪的组成和原理,确定合理的计量特性,对滴定原理土壤有机质分析仪的温度示值误差、温度均匀性、仪器示值误差和重复性等计量指标进行校准,编写具有可操作性的校准方法,并评定校准结果的测量不确定度。针对滴定原理土壤有机质分析仪形成一个较为合理、实用的校准方法,对规范该类仪器的校准具有实际意义。

By studying the composition and principle of the titration of soil organic matter analyzers,the reasonable metrological characteristics are determined,and the metrological indicators such as temperature deviation,temperature uniformity,indication error and repeatability of the soil organic matter analyzers are calibrated.A calibration method with operability is compiled,and the measurement uncertainty of the calibration result is scientifically evaluated.In this way,a more advanced and practical calibration method can be formed,which has practical significance for standardizing this kind of instrument.
