 Product introduction

 The fiber optic gyro adopts high precision gyro sensor, which enhances the survey accuracy and range.  Meanwhile, as there are no moving parts, the anti-vibration is solved effectively. And it can be used for the survey of the high inclination well.

Features:

Aerospace-quality fiber optic gyro sensor

North-seeking automatically.

Good vibration resistance, high stability, calibration convenience

Optional working mode:  Point survey, directional survey, and drop survey

 

 Application

Oil drilling engineering well depth trajectory monitoring Supervise the trajectory in oil drilling project

Coal mine drilling construction

Borehole survey in Geological drilling
