第七章热磁式氧分析器的调整及刻度校正一般地说自动气体分析仪器的调整、校正是相当复杂而繁重的工作。因为一般仪器仪表如电工仪表、热工仪表等目前都有一定的国家基准或工厂标准,只要将被调整的仪表和标准表进行比较,就可以确定刻度。但气体分析仪器却不能这样作,因为一方面目前国家没有气体的标准,其次仪器所分析的气体一般皆不是简单的两元混合气体,多数混合气体具有三种、四种以上的成份,而其中多数非测量组份对仪器的分析精度具有一定影响,另外分析仪器的误差因素较多,也给仪器调校工作带来很 Chapter VII thermo magnetic oxygen analyzer adjustment and calibration calibration In general, automatic gas analysis instrument adjustment, calibration is quite complex and heavy work. Because general instruments such as electrical instruments, thermal instrumentation, etc. There are currently some national standards or factory standards, as long as the instrument will be adjusted and standard table comparison, you can determine the scale. However, gas analyzers can not do this because, on the one hand, there is no standard for gas in the country at present, and secondly, the gas analyzed by the instrument is generally not a simple two-component gas. Most gas mixtures have three or more than four kinds of components, Most of the non-measured components of the instrument has an impact on the analysis accuracy, while the analysis of more error factors, but also to bring the instrument calibration work
