Refraction Reflection Surface Wave MASW Borehole Seismic Survey Equipment 24Channels Digital Seismograph With Geophone
Based on WZG-24 engineering seismograph, WZG-24B Engineering Seismograph is developed as a 24bit instrument under English version WINDOWS operating system. With years of designing and manufacture experiences, and accepting latest electronic technologies and design ideas, WZG-24B features multi-function, high accuracy, high speed, reliable data and good expandability. In addition to WZG-24B main unit, an industrial computer or notebook is also must to collect data and to communicate with it through USB port, in association with an integrated rechargeable battery which can continuously last for eight hours. Seismic source may be hammer, electric spark or explosion. It is extremely suitable for wave velocity testing (sheared wave), surface wave detecting, pier foundation inspection, ground micro-tremor survey, seismic imaging, shake measurement, and reflection and refraction survey. It is extensively applicable in hydrogeology, electric power, railway, bridge, city construction, traffic and other engineering geological field prospecting as well as in exploration of petroleum, coalfield, uranium ore, groundwater and other resources.
