WZG-24C channel seismic refraction equipment is the third generation seismic equipment,which developed as a 24bit instrument under English version WINDOWS 10 system.The system is composed by two parts: the tablet PC and the collecting unit. The data of collecting unit is transferred to PC by USB port. Each parts is powered separately, and the power of the collecting unit is available to switch freely.
Function:
Wave speed (sheared wave) survey
Transient multifold Rayleigh wave prospecting
Multi-wave high density seismic imaging
Shallow refraction survey
Foundation pile inspection
Civil engineering quality detection
Site constant shake survey
Shake-to-blasting survey
