抚顺煤矿安全仪器厂生产的 AQR—1型热催化式瓦斯测量仪和奉化电子仪表厂生产的 KDD—1型热导式瓦斯测定器,是利用热催化燃烧原理和热导原理制造的两种国产新型瓦斯测量仪器。从1972年10月起,这两种仪器各有28台和3台(后来又增加10台),在鹤壁矿务局八矿的瓦斯检查工作中开始应用。他们从大量实践中,考核了仪器的性能,总结出了相应
AQR-1 thermal catalytic gas measuring instrument produced by Fushun Coal Mine Safety Instrument Factory and KDD-1 thermal conductivity gas measuring instrument manufactured by Fenghua Electronic Instrument Factory make use of the principle of thermal catalytic combustion and the principle of heat conduction to produce two kinds of domestically produced New gas measuring instruments. From October 1972 onwards, the two instruments each have 28 and 3 units (later added 10 units), started the application of gas inspection at Hebi Mining Bureau VIII. From a large number of practices, they evaluated the performance of the instrument and summed up the corresponding
