手提式气体分析器苏联中央科研情报所和仪器经济技术研究中心根据自动化和管理系统的资料进行了报导:手提式气体分析器问世。这种仪器能迅速测定汽车发动机废气里的碳氢化合物的成分。气体分析器的制造原理是根据此分析气体对红外线辐射的吸收率进行测量而得出结果。红外线辐射的形成是借助于灯丝和固定的滤光器的联结,穿过被试验的气体,再透过显影盘,最后显示在光敏电阻上.如果试验的气体里没有碳氢化合物,那么光接收器就照样发
Portable gas analyzer Soviet Central Research Institute and the Center for Economic and Technological Research Center based on automation and management information reported: portable gas analyzer available. This instrument quickly determines the composition of hydrocarbons in the exhaust of car engines. The gas analyzer principle of manufacture is based on the analysis of the gas absorption rate of infrared radiation measurements obtained the results. Infrared radiation is formed by means of the connection of the filament with the fixed filter, through the gas being tested, through the development disc, and finally on the photoresistor. If the gas under test is free of hydrocarbons, the light reception The device is still made
