Product Detail
Company Profile

Instruction:

LGT-20DS seismic Geophone is compatible with LGT-20D conventional seismic geophone and its spurious response is greater than 250 Hz for extended clean band width. Its typical string distortion is less than 0.1%. 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. LGT2119 geophones strings are used in a various applications that are far removed from their original applications as earthquake detectors, engineering vabrations, perimeters defensing.
