Detailed Product Description

Seismic Equipment, Seismic Seismograph,

DZQ Series High Resolution Seismograph (Shallow-Layer Seismograph) for Reflection and Refraction Exploration

DZQ Series High Resolution Seismograph (Shallow-Layer Seismograph)

Main Applications

· Reflection and Refraction Exploration: Bedrock embedded depth, shape and regularities of distribution research, hydrological and engineering and environmental geological basic investigation.

· Surface Wave Prospecting: Cover layer investigation; weathering zone investigation; underground cavity and diseased geologic body survey; subgrade, levee, slope disease investigation.

· High-density Multi-wave Seismic Imaging: Cavity investigation of ground base and subgrade (roadbed), cave surveying, etc.

· Quality Inspection of Civil Engineering; Bridge pier and building pile foundation detecting, etc.

· Safety Evaluation of City Blasting Vibration: All kinds of safety monitoring of blasting vibration.

· Shear Wave Velocity Test: Measurement of rock mass elasticity parameters, etc.

Main Features

· Adopt the latest high-speed, high-precision real 24-bit A/D converter. Maximum sampling interval for 48 channels in simultaneous sampling is 31.25us, reaching international advanced level.

· Maximum sampling interval for single channel is up to 10us.

· Not only use the advanced wave filter with ultra-low distortion performance, better than 120 dB, with external suppression (cut-off frequency automatically changes with sampling frequency); meanwhile, various digital wave filters (high, low, band pass wave filters) are set in the software, with their cut-off frequency being set artificially.

· Support coverage measurement;

· Provided with overlaying switch and overlaying cable manufactured by our factory, the application in various reflection, refraction, reflex measurement for field exploration can be facilitated, thus greatly improving the efficiency of field work.

· DZQ48 high-resolution seismograph can support 12-channel and 24-channel overlaying measurement without external configuration
