Namibia DQL-8A Geological Compass

This product is an upgraded version of our company’s DQL-8 geological compass. Through the application of innovative technologies, it boasts several distinctive advantages: the glass cover is now secured with a high-quality rubber gasket instead of a metal compression ring, and the magnetic needle braking mechanism has been rationally designed, enhancing the instrument’s resistance to rain; furthermore, the magnetic needle and designated areas of the azimuth dial are coated with luminous powder, facilitating use in dark environments.

Product Description

1 , Dial: 0°–360°, Graduation: 1°. Steering wheel: the outer ring scale indicates slope (the tangent of a 45° slope in both directions), with a graduation of 0.05; the inner ring scale indicates a slope angle of ±90°, in degrees, with a graduation 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
