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
