测氮仪是医疗和生产、科研广为应用的重要仪器,在医院中它检测人体氮气含量,作判明肺功能障碍之用,在工矿、科研中可检测某种混合气体成份中氮的浓度百分率。但是,目前这种仪器依靠进口,不仅使开展肺功能学科的研究受到限制,而且要花费大量的外汇。我省平阳县仪器仪表厂接受平阳县科委1979年下达的试制任务,从2月开始在上海 Nitrogen analyzer is a medical and production, research and extensive application of important equipment, in the hospital it detects human nitrogen content, for the determination of pulmonary dysfunction purposes, in mining, scientific research can detect a mixed gas composition of nitrogen concentration percentage . However, the current reliance on imports of such instruments not only limits the research on the subject of pulmonary function, but also costs a great deal of foreign exchange. Pingyang County, Instrument and Meter Factory Pingyang Science and Technology Commission to accept trial in 1979 issued a trial task, from February in Shanghai
