Product Descripation:
Our institute makes the engineering seismograph by referring to other advanced seismograph home and abroad. It is true 24-bit and for Chinese WINDOWS. It is not only based on our designing experiences, but also adopt latest electronic technique and design ideal. It is characterized with multi-function, high accuracy, high speed, reliable data and good expandability.
Exciting source can be Hammer, spark or explosion. Exploration depth ranges from a few meters to several hundred meters, and greater deep seismic data can be gained by using time-lapse function. It is applicable for seismic reflection survey, seismic refraction survey, seismic surface wave method, foundation pile inspection, micro-seismic survey, seismic image, shake measurement, and wave speed (secondary wave) testing, is extensively used in hydrogeology, electric power, railway, bridge, urban architecture, traffic and other engineering geology prospecting. The seismograph also can be used for petroleum, coalfield, uranium ore, ground water and other resource exploration..

Features
Fast sampling----true 24-bit A/D, minimum sampling interval: 50μs for 24 channel.
Rendering original signal perfectly----perfect amplitude and phase consistency, low distortion, band outside shearing better than 72dB (shearing frequency point changing with sampling frequency automatically, removing alias completely).
High-speed data transfer----Transmitting data by USB port between internal industrial PC and data collector. Advanced hardware make the sampling and transferring data simultaneously.
