中国科学院上海有机化学研究所、国家地震局地质研究所、江苏省无锡市无线电厂联合研制一种新型气敏仪,经室内测试和井上试用,效果良好。该仪器在今年于北京召开的鉴定会议上审查通过,并正式定名为QJD-A型气敏仪。 该仪器采用气敏半导体做检测元件,对氢和甲烷特别敏感,并采用桥式补偿电路和双气 Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences, Institute of Geology, State Seismological Bureau, Wuxi City, Jiangsu Province, jointly developed a wireless plant gas sensor, the indoor test and upstairs trial, the effect is good. The instrument was examined and approved at the appraisal meeting held in Beijing this year and was officially named QJD-A gas sensor. The instrument uses gas-sensitive semiconductor as a detection element, is particularly sensitive to hydrogen and methane, and the use of bridge compensation circuit and double gas
