Multi-functional Downhole Survey Instrument Borehole Inclinometer Borehole Survey Equipment
The GDP-4T borehole inclinometer consists of two main parts, the survey tool itself and an Android controller that is used to operate and present the borehole survey data. There is a lithium battery inside the probe for the survey tool to get power.
The GDP-4T downhole survey instrument is a magnetic multi-shot survey tool. The electronic unit consists of three magnetometers and three accelerometers. They measure the magnetic field and gravity where the tool is placed along. The sensor data obtained during a survey is stored in the internal memory of the tool and can be downloaded via Bluetooth when the tool is connected to the Android controller.
According to different boreholes, you can use the landing collar or the steel rope to lower the tool down the hole by gravity.
The geotechnical inclinometer 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.
