The Harbin Geological Compass DQL-8 is a precision navigation instrument designed for field geology and mineral exploration. It incorporates a damping function that stabilises the needle within nine seconds, allowing rapid readings. The needle is fabricated from neodymium‑iron‑boron (NdFeB) permanent magnet material, providing the highest magnetic strength among compact compasses. Accuracy is reported as less than 0.5 degree error, supported by a magnetic declination adjusting knob and a needle‑lock button for fixed readings.
The device is machined on a German DMG 5‑axis centre, ensuring tight dimensional tolerances and consistent performance. Each unit undergoes 100 % inspection with 200 quality‑control checkpoints, covering magnetic alignment, mechanical integrity and surface finish. The housing receives an electrostatic spraying process that delivers anti‑rust and anti‑corrosion protection, extending service life in harsh environments. Typical geological compasses of this class are rated for an operating temperature range of - 20 °C to +50 °C and a weight of about 250 g, which matches the DQL-8’s portable design.
Buyers such as surveying firms, mining companies and academic research groups often request calibration certificates and detailed test reports. Trade terms, including minimum order quantity, price and Incoterms, are not disclosed in the listing and should be confirmed directly with the supplier. The Harbin Optical Instrument Factory Ltd. can arrange bulk shipments from its Harbin facility, subject to agreed payment and logistics arrangements.

Before placing an order, request the latest calibration certificate, the detailed 200‑point QC report and material certification confirming the NdFeB needle composition. Verify that the electrostatic spray coating meets the anti‑corrosion standards required for your operating environment. If possible, obtain a functional sample to assess damping performance and declination adjustment smoothness.
Discuss logistics early: confirm the minimum order quantity, expected production lead time and the preferred Incoterm, such as FOB Harbin or CIF Shanghai. Payment terms are typically negotiated as T/T or L/C; ensure the supplier’s banking details are verified before transaction. Align shipping method with cargo volume, whether by air freight for small batches or sea freight for larger consignments.
Plan for quality assurance by arranging a third‑party inspection at the Harbin facility or during pre‑shipment. Request test reports for magnetic accuracy, corrosion resistance and dimensional compliance. Ensure that all documentation, including the inspection certificate and the supplier’s export licence, accompanies the shipment to facilitate customs clearance.
