WZG-24/48 Introduction
Engineering seismographs, also known as shallow seismographs, generally refer to seismic exploration instruments with an exploration depth of nearly hundreds of meters. Engineering seismographs can be used for refraction exploration, in-hole PS logging, cross-hole seismic, and serve engineering construction. It can also be used as a data acquisition system for multi-channel transient surface wave exploration. The entire system is small, light, and easy to transport. It can work anywhere using a small 12V DC voltage battery.
Advantages:
1.potable:Wireless integrated design, small size, and light weight.
2.Low energy consumption:The device has a built-in large-capacity lithium battery with ultra-long battery life
3.High-resolution:Built in2Hz high sensitivity geophone behave better in deep-depth detection
4.Low noise level:1µV(full-frequency)withwide dynamic range and ultra-low noise level.
5.Support coverage measurement: When used with the PZF-36A coverage switch and PZF-60A coverage switch produced by our institute, it can easily realize various field coverage measurements, greatly improving the efficiency of field shallow reflection seismic exploration operations.
6.Reasonable structural layout: the instrument has good vibration resistance, moisture resistance and dust resistance

The instrument uses hammering, electric sparks or explosions as the excitation source, and the exploration depth ranges from a few meters to hundreds of meters. The time delay function can also be used to obtain seismic data from deeper strata. It is very suitable for seismic work such as reflection, refraction, surface wave exploration, pile foundation detection, ground pulse measurement, seismic imaging, vibration measurement and wave velocity (shear wave) testing. It is widely used in engineering geological exploration in the fields of water conservancy, electricity, railways, bridges, urban construction, transportation, etc. It can also be used in resource exploration in the fields of oil, coal fields, uranium mines and groundwater.
