Product Detail
Company Profile

Instruction:

LGT-SM seismic Geophone is designed to offer cost-effective performance in seismic exploration, main parameters controlled within ± 2.5%. Low distortion, combined with durable specifications, provide high-fidelity data in 2-D and 3-D surveys. It has 3-year limited warranty.

Features:

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