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。
SD-3A automatic radon detector is the digitized, high-sensitivity and stable performance instrument developed under the guidance of the monitoring department of China Seismological Bureau during the Ninth Five-year Plan. It is applicable to the continuous and automatic observation of radon in many environments. In the development of the scintillation chamber was a bold innovation, the Zn S (Ag) screen using new technology and high-tech processing, completely solve the problem of moisture-proof Zn S (Ag), while greatly improving the corrosion resistance, significantly extended The flicker room life, broaden the application environment. The main machine selects the powerful 51 series single-chip micro-core 89C52 as the core, as long as the power is turned on, enter the choice of parameters, the instrument can be long-term operation, output reliable data into the earthquake transmission network can be transmitted, Radon monitoring preferred instrument.
