Namibia HGC-6 Gold Geological Compass

This instrument utilizes a magnetic object—the magnetic needle (which features a special design to shorten the needle’s stabilization time and enhance measurement efficiency)—to indicate a specific direction along the magnetic meridian. By reading the scale ring, one can determine the azimuth of a target relative to the magnetic meridian. Based on two selected survey points (or known reference points), the position of an unknown target can be calculated. The instrument is capable of measuring structural orientations, including strike, dip, and dip angle; conducting topographic surveys, such as determining orientation via intersection positioning, measuring slope angles and gradients, establishing horizontal planes, and measuring vertical angles. A magnetic declination adjustment screw is provided on the exterior of the instrument housing. This instrument boasts a compact structure, small size, and light weight. Its housing is manufactured by die-casting and finished with a sand-textured paint coating that offers excellent adhesion, a high-end appearance, corrosion resistance, impact resistance, portability, reliable accuracy, and stable performance. Moreover, the instrument’s magnetic needle and spirit level are durable and of superior quality.

Product Description

1. Graduated dial: 0°–360°, graduation interval: 1°. Steering wheel: the outer ring is刻ed with slope indications (the tangent of a 45° slope in both directions), with a graduation interval of 0.05; the inner ring is刻ed with slope indications for 90° slopes in both directions, in degrees, with a graduation interval of 1°.

2. The damping time of the magnetic needle (the time it takes for the needle to deflect by 90° and then come to rest in its original position) is less than 15 seconds.

3. Reading error:

a. The angular error between the readings before and after the magnetic needle rotates shall not exceed 0.5°;

b. At 0°–180° and 90°–270°, the error caused by eccentricity in the magnetic needle shall not exceed 0.5°;

c. The reading error of the protractor shall not exceed 0.5°.

4. Spirit level sensitivity:

a. Long level vial: 15′ ± 3′ per 2 mm

b. Circular level: 30′±5′/2mm

5. Instrument external dimensions (length × width × height): 80 × 70 × 35 mm

6. Instrument weight: 0.24 kg
