Application

Type DZQ12-2A geological seismometers can used hammering and explosion as artificial seismic sources. Measuring depth ranges from a few to thousands of meters. Operators can also use the delay function to acquire seismic data of deeper underground zones. Type DZQ12-2A geological seismometers are widely used for engineering geological investigation of hydraulic engineering, electricity, railways, bridges, civil construction and traffic etc. They can also be used for resource exploration of oil, coal, uranium and underground water etc.
