GDX-3A Borehole Digital Inclinometer

Purpose:

The instrument is specially designed and made to determine dip angle and azimuth angle of borehole in the non-magnetic area. It is suitable for determining dip angle and azimuth angle of borehole, which should be more than 65 mm in diameter, non-magnetic and without casing tube. Then it can determine inclination and inclination direction of borehole.

The instrument has been widely used for inclination measurement in the field of engineering, hydrology, oil field, coal field, and geology.

Technical parameters:

1. Power supply: 90 V;

2. Dip angle measurement:

(1) Measurement range: 0°～50°;

(2) Scale division: 30′;

(3) Measurement error: ±30′;

3. Azimuth angle measurement:

(1) Measurement range: 4°～356°;

(2) Scale division: 5°;

(3) Measurement error: not more than ±4°;

4. Pressure endured by inclinometer probe: 50 MPa;

5. Maximum temperature for inclinometer probe: 100 ℃; Maximum temperature for controlling case on the ground: -20℃～+50℃;

6. Inclinometer probe:

(1) Diameter: 54 mm;

(2) Length: 145 cm (not including extending tube);

(3) Weight: 20 kg;

7. It makes determination using point measurement methods. You can read out dip angle and azimuth angle directly on the controlling case. It can make determination at multi-points in the borehole.
