DQG—1A型微量CO、CO_2连续自动分析仪,是为适应小化肥生产发展需要,在文化大革命中研制生产的。它是我国同类型仪器批量生产中最早的一种,对小合成氨生产起到一定的作用。我省现有该型仪器近30台,其中有70年早期的产品,也有75年近期的产品。由于仪器部分结构尚不够完善及使用的问题,我省除了部分化肥厂使用较为正常,零点较为稳定,灵 DQG-1A trace CO, CO_2 continuous automatic analyzer, is to adapt to the needs of the development of small fertilizer production, development and production during the Cultural Revolution. It is one of the earliest batch production of the same type of instruments in our country and plays a certain role in the production of small synthetic ammonia. Nearly 30 sets of this type of instrument in our province, of which there are 70 early products, there are 75 recent products. As part of the structure of the instrument is not yet perfect and the use of the problem, except for some of our province use more normal fertilizer plant, the zero is more stable, Ling
