hoekmeter
A hoekmeter is an instrument used to measure angles. The term is Dutch, composed of "hoek" (angle) and "meter" (measurer), and can refer to a range of devices from simple protractors to precision electronic inclinometers and goniometers. Hoekmeters are used to determine the magnitude and sometimes direction of an angle in a plane or between surfaces.
Simple hoekmeters include the flat protractor, typically graduated in degrees, and bevel protractors used in metalworking.
Accuracy and resolution vary with design: basic plastic protractors suffice for informal use, precision mechanical or
Calibration and correct mounting are important for reliable measurements. Environmental factors such as vibration, temperature and
Applications of hoekmeters span carpentry, machining, surveying, structural engineering, navigation, photography and medicine (for joint angle
