LGT-15D Omni Seismic Geophone

Seismic Geophone

Instruction:

LGT-15D seismic Geophone is omnidirectional seismic geophone. All operating parameters are confirmed with a proprietary computerized test system during

the manufacturing process. It can work properly at any angles.

Features:

It features stable performance, high fidelity and consistent quality in conventional industrial of coal, Petroleum and natural gas exploration.
LGT-15 geophones are used in a various applications that are far removed from their original applications as earthquake detectors,
engineering vibrations, perimeters defensing.
