Azimuth Circle of Magnetic Compass
Overview
Standard: GB/T335-2005.
Main technical data
Temperature range: -30℃~+60℃
Deviation between the sight mark line on the prism box and the graduation zero line: ≤0.06mm
Deviation between the central line of the sight seam and the sight mark line: ≤0.5mm
Deviation between the sight seam and the sight line: <12’ (the left and right); <1’’ (in front and behind)
Material: high quality non-magnetic material
Azimuth circle can rotate easily on the compass and should not produce a sidewise motion leading a reading error of more than 2’’
