Features:
1The sextant is an accurate angle measuring instrument, which consists of three parts: the frame body, the optical system and the angle reading device. 2The optical system includes a telescope, a moving mirror, a fixed mirror and a filter; the angle reading device has an indexing arc, an index rod, a drum wheel and a vernier scale. 3These components are mounted on the frame and the optical system and the angle reading device are integrated into one unit via the indicator rod. 4The sextant is based on the principle that the geometrical "outer angle of the trigonometry is equal to the sum of the two adjacent inner corners", "the angle of the parallel line is equal", and the "central angle can be measured by the arc distance of the circle". 5Professional manufacturing, stable performace, high reliability.
