40mm Small-bore Digital Compass Declinometer for Gradient

  40mm Small-bore Digital Compass Declinometer for Gradient

Purpose: 

The instrument is designed and made for inclination measurement and direction control during engineering drilling, exploration drilling and directional drilling. Combines sensor, power supply, data processing system, and other controlling unit together, it can independently determine dip angle and azimuth angle of borehole at multi-points. No cable is needed. No mechanical moving parts. It is reliable and with high performance price ratio. It has been widely used in engineering, hydrology, oil field, coal field, and geology.
