Product Description

Seismic Refraction Test Equipment  Geophysical MASW/Refraction/Reflection Seismograph with Geophone

Our institute makes the engineering seismograph by referring to other advanced seismograph home and abroad. It is true 24-bit and for 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.. 

The Application about Seismograph:


REFRACTION

SHALLOW REFLECTION

SURFACE WAVES (MASW, Re.Mi., Vs30, MAAM, ESAC, etc.)

HVSR / VIBRATIONS

DOWNHOLE (with 3D borehole geophone )

 CROSSHOLE (with 3D borehole geophone  and cross-hole energizer for P/S waves )

Details:
Seismic Cable:12/24chanel, 5m spcae or 10m spece for optional(Accept Custom)


Seismic Sensor(Geophone): 4.5HZ/10HZ/ 3C Geophone String, Borehole Geophone for optional
