โทรศัพท์มือ 5 รุ่นใหม่ (ZF-2)

SG-5 is a new geophone featuring a high-sensitivity and a low natural frequency. This new sensor offers comparable output sensitivity to an array of geophones while providing lower frequency recording capabilities down to 5Hz.

Especially designed for single sensor application, SG-5 is particularly adapted for microseismic operations in combination with UNITE but also fully compatible with existing Sercel 428XL cable system.
