钠表,既钠离子计,用来测定钠离子浓度的仪器,广泛应用于热电厂及其他工业锅炉水、蒸汽冷凝水等的检测分析。采用离子选择电极,从电极电位的变化来检测溶液中被测离子浓度的变化。本文针对HACH公司的9245钠分析仪、ABB的8037型钠分析仪及核工业北京化工冶金研究院的HGY2068钠分析仪3个厂家的钠分析仪的在线运行中的测量原理、技术指标、操作校准、维护和故障处理等方面对比优劣,提出维护建议。
Sodium meter, both sodium ion meter, used to determine the sodium ion concentration of the instrument is widely used in thermal power plants and other industrial boiler water, steam condensate water, such as the detection analysis. Ion-selective electrodes are used to detect changes in the measured ion concentration in solution from changes in electrode potential. This article aims at the HACH’s 9245 sodium analyzer, ABB’s 8037 sodium analyzer and nuclear industry Beijing Institute of Chemical Metallurgy HGY2068 sodium analyzer three manufacturers of sodium analyzer in-line operation of the measurement principle, technical indicators, operation calibration , Maintenance and troubleshooting and other aspects of the pros and cons, proposed maintenance recommendations.
