Product Description

6/12 channel Seismograph for land survey Refraction, Reflection, MASW, MAM, Downhole, VSP for Surface geophysics and exploration


Seismographs for Seismic Refraction Reflection MASW Downhole Crosshole


WZG-6A/12A is a 24-bit wave velocity tester, under Windows Operation System, based on WZG-24 engineering seismograph. It features multiple function, high precision, high speed, high reliability and fine expansibility.

Industrial PC or notebook PC is required to collect data through USB interface; built-in rechargeable battery ensures the instrument to work for over 8 hours. Seismic source for testing may be hammer, electric spark or explosion, extremely fitted for sheared wave velocity test, surface wave exploration, pier foundation test, ground micro-tremor measurement, seismic imaging, shake measurement, and refraction or reflection survey.

Applications:

It applies to engineering geological prospecting, in various fields such as hydrology, electricity, railway, bridge, city construction, traffic, etc, and in petroleum, coal, uranium and groundwater exploring.

Functions:
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
