Introduction
A-DZQ48D high resolution seismograph is the new 24 digital equipment worked under WINXP system. It integrates our many years manufacturing experience and advanced electronic technology and design idea at home &abroad, then it has multiple functions, high precision, high speed, high reliability, perfect man-machine interface and expandable. The prospecting depth is from 1m to thousands of kilometers, you can use time delay function to gain more deep seismic information, and the applied methods are: reflection, refraction, surface wave exploration, pile testing, earth pulse measurement, high density earthquake imaging, tremor survey and shearing wave testing etc. It is widely used in the engineering geological prospecting of water conservancy, electric power, railway, bridge, city building and traffic etc., also resource survey in oil, coalfield, uranium ore and underground etc.
