Import Forest Compass Harbin Survey Compass — Buy in wholesale FOB from Supplier in China

The Forest Compass Harbin Survey Compass is a dedicated surveying instrument manufactured by Harbin Optical Instrument Factory Ltd. It carries the Harbin brand and model designation DQL-16Z. The device integrates a 16X telescope with an erect lens diameter of 22 mm and a 1 : 100 stadia field of view, providing a 2 deg view at a shortest sighting distance of 2.5 m. The compass module features a 67 mm needle length, 1 deg dial resolution and a needle accuracy of ±0.5 deg.

The instrument’s optical components are assembled from standard optical glass and the housing is fabricated from a typical aluminium alloy, offering resistance to corrosion in forest environments. Horizontal and vertical vernier scales each resolve to 5 min, while the vertical scale spans a measuring range of ±50 deg with a precision of 2 mm at 30 m. The net weight of 800 g (without case) and compact dimensions - telescope 140 mm, compass 105 mm, overall height 230 mm - meet common portability standards for field survey equipment. A tripod is supplied as an accessory, matching the usual practice for stable observations.
