MCS-805型脉冲库仑定氧仪于76年通过鉴定后,已生产了二百台。它遍及全国冶金、航空,机械及国防等系统的工厂及科研单位。该仪器除了有许多公认的优点外,还存在某些不足之处,特别是空白值和气路系统方面反映的问题最大。我们认为空白值的高低和气路系统的结构是有密切联系的,我们针对原仪器在气路系统方面存在的三个问题进行了改进,同时也改进了分析方法,降低了分析空白值,扩大了仪器的测量下限,成功地分析了含氧量为1ppm的无氧铜,达到了国际同类型仪器的
MCS-805 Pulse Coulomb Oxygen Meter passed the appraisal in 76 years, has produced 200 sets. It is throughout the country’s metallurgical, aviation, machinery and defense systems, factories and research institutes. In addition to many of the recognized advantages of this instrument, there are certain drawbacks, notably the largest number of problems reflected in terms of blank values and pneumatic systems. We believe that the level of the blank value is closely related to the structure of the gas circuit system. We have improved the three problems in the gas circuit system of the original instrument, and also improved the analysis method, reduced the analysis blank value, expanded The lower limit of the instrument, the successful analysis of the oxygen content of 1ppm of oxygen-free copper, reached the international same type of instrument
