Sextant
Product Code : EL-LE-12134
Eduscope India is a leading Sextant
Quick Answer: The Sextant is mainly used to measure and determine the dimensions of inaccessible objects - such as the height of a mountain or building, the diameter of the sun, or the distance between two points - and is also used for marine navigation.
As a physics lab equipment India resource for surveying and navigation teaching, the optics and mirrors are carefully selected for high vision accuracy, and the instrument is built entirely from brass with a stainless steel arc scale. Dimensions are found by determining the angle subtended by two different objects at the point of observation, with true angles measured in accordance with international standards down to 12 seconds.
