Harbin DQL*8 Geological Compass withhighemagneticNeddleand non-magnetic body

The geological compass works on the principle that the magnet needle points in the direction of the bright magnetic meridian, thereby determining the azimuth of the target. The key role of magnetism in a compass is self-evident.

Harbin DQL*8 geological compasssmagnetic needle, which is the soul of the compass, is made of NdFeB magnet. NdFeB magnets are the strongest permanent magnets at room temperature by far. (second only to holmium magnets at absolute zero, but far more magnetic at room temperature than all known permanent magnets). It help compass keep working for long time without Demagnetisationand the housing components adopt a zero-magnetic process to eliminate any influence on the magnetic needle.

Components other than the magnetic needle are made of non-magnetic materials and processes, such as screws, which are made of copper with an iron content of less than 0.5%, and are treated with non-magnetic plating to achieve zero magnetic content in the components so as not to affect the working of the magnetic needle. The accuracy of theHarbin geological compass is ensured by the strict control of the magnetic material.

The DQL*8 geological compass is designed with the following parameters: 0°***0° for the dial and 1° for the grid. Directional dial: the outer ring scale indicates the slope angle with a value of 0.*5; the inner ring scale indicates the slope angle with a value of *0° in both directions with a value of 1°. Magnetic needle damping time less than *5 seconds. The error of the reading is not more than 0.5° before and after the rotation of the magnetic needle; the error caused by the eccentricity of the magnetic needle at 0°***0° and *0°***0° is not more than 0.5°; the error of the reading of the goniometer is not more than 0.5°.

Harbin DQL*8 geological compass, with magnetic core and non-magnetic body, such a high precision compass, you deserve to try.
