Import Harbin Geological Compass Brunton Type — Buy in wholesale FOB from Supplier in China

The Harbin Geological Compass Brunton Type is a precision navigation instrument manufactured by Harbin Optical Instrument Factory Ltd. in Harbin, Heilongjiang, China. The company reports that this model holds a 95 % share of the domestic geological compass market and has been produced under the national and industry standard for geological compasses since 1966. The compass features a brass base with a protective aluminium alloy case and a graduated circular scale marked at 2° intervals. It incorporates a magnetic declination adjustment mechanism that rotates through a full ±180° range.

The case is typically aluminium alloy, offering corrosion resistance suitable for field conditions. The sighting system uses a mirror with a sighting slit, a configuration standard across Brunton‑style compasses. Typical accuracy for such instruments is ±2° without external calibration, and the device includes a built‑in clinometer for dip measurement. These characteristics align with the specifications commonly required by geological survey teams and academic field programs.

Field geologists, mining engineers and environmental consultants use this compass for structural mapping, fault orientation and mineral exploration.
