Seismograph Microtremor Geophone 2Hz 3 Component Geophone 2Hz 3c Seismic Sensor Trixial Seismic Geophone Seismic Sensor Seismic Survey Geophone
It used for deep seismic survey, natural earthquake prediction monitoring and the measurement of bridge, dam, road and other micro pulse
It owns good parameter consistency, solid body, good sealing and light weight. Each Geophone Operating Manual signal output separately, which has high sensitivity, low distortion, reasonable damping factor and higher resolution. So, it is able to meet the requirement of the multicomponent seismic wave data collection. It wildly used for public infrastructure (roads, railway tunnel), security monitoring.It is popular in Japan, South America and other regions.

High consisteney in parameters, secure structure, good waterproof sealing, separate output of each component signal, high sesibilit, low distortion, reasonable damping cofflcient and high resolu tion; be able to meet technical requirements for multi-component seismic data cllctin. In conjunction with related instruments, this product series has been extensively used in the atifcial seismic exploration for seismogenic structure in the earthquake dangerous zone in southeasterm partofGansu province, China and in the exploration for active fault in Xi an city as well as in the exploration for the refined structureof ithoisphere in the orogenic zone of Yin mountain and for the deep dynamic process. This product series also has been extensively used in national key projects, such as 863, 305, 973 and others, obtaining useful data infrmation for China's earthquake monitoring.
Good parameter consistency, firm mechanism, good sealing, each geophone signal output separately, high sensitivity, low distortion, reasonable damping coefficient, high resolution, can meet the requirements of multi-wave component seismic data acquisition technology. At the same time, he participated in the field exploration project of "Studying the structure and properties of Lithosphere in the Northern North China Craton by using wide-angle reflection/refraction Profile with ultra-long observation distance", and the field exploration project of "Wide-angle reflection/refraction and high-resolution refraction detection of deep earthquake in the middle section of Longmenshan Fault". At the same time, this series of geophone has been used many times by the national 305 project of the Institute of Geology and Geophysics of Chinese Academy of Sciences, the National 863 project of the Institute of Earth Sciences of China Earthquake Administration, and the Geological Academy of the Ministry of Land and Resources.
