摘要
SD- 3A自动测氡仪是“九五”中国地震局监测司指导下研制的数字化、高灵敏度、性能稳定的、适用多种环境下的连续自动观测气氡的仪器。研制中对闪烁室进行了大胆的革新 ,对 Zn S( Ag)屏采用了新工艺和高科技技术处理 ,彻底解决了 Zn S( Ag)防潮难题 ,同时大大提高了抗腐蚀能力 ,大幅度延长了闪烁室的寿命 ,拓宽了应用环境。仪器主机选用了功能强大的 51系列单片微机芯 89C52为核心 ,只要接通电源 ,输入各项选择参数 ,仪器即可长期运行 ,产出可靠数据 ,入地震传输网即可传输 ,是对气氡监测首选的仪器。
The SD-3A Auto-radon detector is a kind of digital,sensible and stable instrument which can automaticaly measure gas radon under various conditions.The scintillant chamber is renovated and some new techniques are used to the ZnS(Ag)screen,which makes the instrument damp-proof and anti-erosion.The lifetime of the scintillometer has been extended and the application environment has been widened.The scintillomenter has a 51 series of microcomputer with a powerful 89c52-core.As soon as connected to the power and inputted necessary parameters,the instrument can run for a long time and reliable data can be obtained.The data can be transmitted when the instrument is connected to seismological web.The instrument,therefor,should be the first choice for measuring gaseous radon.
