JSZ-2型自动测氡仪是观测地下水中氡气浓度连续变化的重要设备。整套仪器由玻璃质连续脱气装置,时间程序自动控制装置,闪烁探头脉冲计数装置和数字重复打印记录装置构成。仪器按震情能进行间歇或连续观测,最高可测水氡1000埃曼,误差<±10%,观测结果和时间同时打印表出。Q_水=2.0升/分,Q_气=200～450毫升/分,灵敏度～800脉冲/分/埃曼,脱气效率～50%。通过各种条件试验和地震现场及定向爆破观测考核,该仪器与国内外类似连续测氧仪相比,具有直观性好,灵敏度高,准确可靠,操作简便等特点;尤其是玻璃质脱气装置更具有抗腐蚀,易清洗,成本低等优点。故利于普及推广,基本上满足当前水氡观测工作和地震予报的要求。
JSZ-2 automatic radon detector is an important equipment for observing the continuous change of radon concentration in groundwater. The whole set of equipment consists of glass continuous degassing device, time program automatic control device, scintillation probe pulse counting device and digital repeat printing record device. The instrument can be intermittent or continuous observation by earthquake conditions, the maximum measurable water radon 1000 Aman, error <± 10%, the results of the observation and the time printed out at the same time. Q_water = 2.0 L / min, Q_gas = 200-450 mL / min, sensitivity ~ 800 impulses / min / Aman, degassing efficiency ~ 50%. Through a variety of conditions and field observation of seismic and directional blasting observations, the instrument with similar domestic and foreign similar continuous oxygen meter, with good intuitive, high sensitivity, accurate and reliable, easy to operate and so on; especially the glassy degassing device More corrosion-resistant, easy to clean, low cost and so on. It is conducive to the popularization and promotion, basically meeting the current water radon observation work and earthquake report requirements.
