EG-15-OD-I geophone is a kind of geophone which can work at omni-directional.
Omnidirectional high temperature geophones are used in petroleum exploration, well logging exploration, industrial vibration monitoring and other fields.
- Any angle of 0 ~ 360° can be used;
- It has the characteristics of low damping, high sensitivity, small size and light weight;
- Sustainable use under -40°C ~ +80°C environment;
- Unique technology and process, the performance of the detector is more stable in high temperature environment.
