Product Detail
Company Profile

Instruction:

LGT seismic geophone element is designed to offer long service life in seismic exploration, its bandwidth is from 10 Hz to 190 Hz in 2D and 3D seismic exploration. and it can be installed in variety of LGT geophone cases.

Features:

It features stable performance, high fidelity and consistent quality in conventional industrial of coal, Petroleum and natual gas exploration. LGT seismic geophones are used in a various applications that are far removed from their original applications as earthquake detectors, engineering vabrations, perimeters defensing.
