摘要
介绍DL系列卡氏法自动水分滴定仪的校准方法,提出了须校准的项目及其技术要求,并对示值误差测量结果的不确定度进行了分析评定,得出示值误差测量结果的不确定度为U_(95)=1.5％,有效自由度V_(eff)=21。
A method calibrating DL series Karl - Fischer auto moisture titration instrument is introduced, subjects being calibrated and their technical requirements are put forward, the uncertainty of the measurement result of the indication error is analyzed and evaluated. This uncertainty is U95 = 1.5% , veff = 21.
