摘要

介绍扩散型和平衡型两种溶解氧测量传感器的测量原理

指出它们的共有测量误差来源及防止措施

并介绍了3种溶解氧测量仪的校正方法以及测量时的注意事项。

Abstract

The measuring principles of two sensors for measuring dissolved Oxygen have been presented

the influence of flow velocity

surface contamination

anode aging

and gas bubbles in the sensor upon difusion type sensor used for measuring dissoved oxygen being analysed

the common source of measuring error and prevention measures for the two said sensors being pointed out

the calibration method and points needing to pay attention at the time of measurement for three instruments used for measuring dissolved oxygen being also presented.
