Purpose:

The instrument is designed to make inclination determination and directional control for engineering borehole, exploration borehole and directional borehole in the magnetic area. The instrument integrates sensor, power supply, and data processing system together to determine dip angle and azimuth angle of borehole in single/multi-point mode. It is not required to use cable and there is no mechanical moving part, so it is reliable and has high performance price ratio. It can be widely used in engineering, hydrology, oil field, coal filed, and geology to determine dip angle and azimuth angle of borehole.
