WZG-12A Surface Wave Tester

　　WZG-12A is developed based on WZG-24 engineering seismograph which is Chinese WINDOWS based and 24-bit. It embodies not only the seismograph design experiences of our institute, but also the modern electronic technique and design ideals. It is of multi-function, high-precision, high-speed, high-reliability and fine expansibility. It is truly a refined one of all kinds of seismographs.

　　Industrial computer or laptop computer is required for operation through simple connection of USB port. Built-in rechargeable battery can ensure more than 8 hours work. Seismic source can be hammer, electric spark or dynamite, so that it is fitted for surface wave exploration, shear wave velocity test，pier test, earth vibration measurement, seismic imaging, shake measurement, refraction or reflection survey. It is extensively applied in engineering exploration, such as irrigation works, power, railway, bridge, civil construction, traffic, etc.. It can also be used in ground water and energy exploration, such as petroleum, coal, and uranium.
