研制了一种微量水份分析仪,仪器采用卡尔-费休尔试剂,以库仑滴定原理测量物质所含表水和结晶水。介绍了仪器的主要电路设计。用两种方法测量了仪器的准确度,相对误差均不超过3％。
Developed a trace moisture analyzer, the instrument used Karl Fischer reagent to measure the substance contained in the Coulomb titration water and crystal water. The main circuit design of the instrument is introduced. The accuracy of the instrument was measured in two ways, with relative errors not exceeding 3%.
