Harbin Compass Magnetic Needle made of best magnet

The magnetic needle is the soul of the compass, and the core component of the geological compass is the magnetic needle. The magnetic needle in Harbin DQL*8 geological compass is made of a precision NdFeB disc magnet, which makes the compass accurate and avoiding demagnetised.

The magnetic needle must be made of a permanent magnetic material, so if a poor quality magnet is used, the performance of the needle will be far worse. At the same time, in the production process of magnetic needles, the process and processing equipment also have a huge impact on the quality of the final product, although customers do not have direct access to the magnetic needle, but the most important key indicators in use will expose the defects of the magnetic needle.

According to a geological survey expert, who previously used the famous brand Brunton compass. Now he find that Harbin compasss indicators and accuracy can be competitive to Brunton after using and comparing both of them. He communicated with the chief engineer of Harbin, got to know Harbin compas and Brunton compass both use NdFeB magnet as needle.

In addition, Harbin geological compass has been specially designed with a magnetic needle lock function, which extends the life of the product. Both the compass magnetic needle and goniometer have an error of less than 0.5 degrees, a damping time of less than *5 seconds and a fast needle stop. Such specification will surely not less than other brand.

Harbin made hundreds of technical improvements and innovations over the past *0 years on the magnetic needle. The small magnetic needle contains Hrbin spirit to improve, and is a great credit to the reputation of Harbin Brand for decades.
