Product Description

CDJ Series Digital Seismic Geophones & Seismic Sensor

Description

CDJ Series Digital Seismic Sensor (Geophone) are available frequencies from 1Hz to 100Hz vertical and horizontal direction, and geophone-consisted three-component geophones, borehole geophone, tomographic imaging geophone series with stable performance, high fidelity and consistent quality in oil, gas exploration and other fields.

Applications and Features

1~3Hz geophones applied for deep seismic prospecting, natural earthquake surveillance and prediction, pulse and microseismic measurement for bridge and highways, etc.
4~100 Hz widely used to seismic prospecting of petroleum, coal, metallurgy, defense engineering and etc.
High sensitivity, low-distortion, reasonable damping coefficient, good linear response, good parameter conformity, higher resolution and excellent waterproof property.
Small-sized, easy to install, easy to operate, large ambient temperature range, can meet the demand of multi-wave component seismic data acquisition technology
