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.
