摘要
提出了一种基于分光光度法的实验室水质色度测定仪校准方法,校准参数包括示值误差、测量重复性和零点漂移。评定了示值误差校准结果的不确定度,同时依照建立的校准方法对实验室水质色度测定仪进行了校准试验。实验结果证明了该校准方法的可行性。该方法可作为评价实验室水质色度测定仪计量性能的有效方法。
A calibration method of laboratory water colorimeters based on spectrophotometry is proposed. Calibration parameters consist of indication error, repeatability and zero drift. The calibration uncertainty of indication error is evaluated. According to the calibration method calibration experiments of laboratory water colorimeters are carried out. Experimental results show that the method is feasible and can be used as an effective method for the metrological performance evaluation of laboratory water colorimeters.
