Angle-measuring instruments may be classified into four types according to the measuring method used. The first group includes devices that compare the angle to be measured against a fixed gage, such as an angle gage (for angles 1â to 180Â°), try square (usually for a 90Â° angle), tapered plug gage, or template.
Universal bevel protractors are also used by toolmakers, as they measure angles by mechanical contact they are classed as mechanical protractors. The bevel protractor is used to establish and test angles to very close tolerances. It reads to 5 minutes or 1/12Â° and can measure any angle from 0Â° to 360Â°. The bevel protractor consists of a beam, a graduated dial and a blade which is connected to a swivel plate (with Vernier scale) by thumb nut and clamp.
