北京分析仪器厂研制的QGS-05型微量二氧化碳红外线气体分析器于今年3月底在南京进行了现场鉴定。参加鉴定会的有分析仪器制造厂、化工设计院和化肥厂等27个单位。 QGS-05型二氧化碳红外线分析器是双光源,双光路型直读式仪器。采用了干涉滤光片提高仪器的抗干扰能力。对检测器的结构也进行了较大的改进。由于采用了较好的充气工艺,检测器温度系数小。仪器不需要恒温,启动时间短,长期稳定性好。电气部件采用了半导体线路。仪器为非防爆结构。
Beijing Analytical Instrument Factory developed the QGS-05-type trace carbon dioxide infrared gas analyzer at the end of March this year, conducted a field test in Nanjing. To participate in the appraisal will have analytical equipment manufacturing plants, Chemical Design Institute and fertilizer plants and other 27 units. QGS-05 carbon dioxide infrared analyzer is a dual light source, dual optical direct-reading instrument. Interference filter used to improve the anti-jamming capability of the instrument. The structure of the detector has also been greatly improved. Due to the better aeration process, the detector temperature coefficient is small. Instrument does not require constant temperature, start-up time is short, good long-term stability. Electrical components using a semiconductor circuit. Instrument is non-explosion-proof structure.
