摘要
提出了一种在空气中测量覆膜电极溶解氧测定仪示值误差的方法。首先分析了相关的理论基础,并且介绍了覆膜电极溶解氧测定仪及其示值误差的检测原理,分析了JJG 291-1999《覆膜电极溶解氧测定仪》中示值误差检定方法的不足之处,提出了采用操作简单,准确可靠的空气测量法,能够实现覆膜电极溶解氧测定仪示值误差的检定。
In this article the authors proposed a method for measures indication error of film electrode dissolved oxygen meter：air calibration. Firstly they analyzed the basle theory and presented a description of this method. They also analyzed the method of the JJG291-1999 （Film Electrode Dissolved Oxygen Meter）.Tne results show that this method （air calibration） is practical for measuring indication error of film electrode dissolved oxygen meter.
