Product Details

Vertical Seismograph Geophone String

Geophone String is our flagship product,Its features below:

Easy maintenance, strong resistance to harsh environment, reliable waterproof performance,
high construction efficiency,
Assembled structure, easy to maintain, rubber waterproof caps at both ends of the wire, prolong the service life of the cable.
The self-tapping screw assembly structure of the upper and lower shells makes field maintenance more convenient and quicker.
The shell material of high strength and low water absorption material is suitable for the harshest environments,
