The utility model discloses a caliper gauge for the examination of sector split conductor elements. The caliper gauge is formed by vertical combination of an arc plate with an arc groove and an angle plate with an angle groove. According to the caliper gauge, the structure of the vertical combination of the arc plate and the angle plate is employed, the process dimension of the sector formed by the arc groove and the angle groove and the process dimension of the sector elements are the same, the structure is simple, the carrying and the usage are convenient, the measuring error is small, and problems that the sector angle, the bottom angle and the arc surface of the sector elements cannot be measured, the measuring error is large, the quality cannot be well controlled, great waste is caused due to sampling, and dimension variation in the process of production and machining cannot be discovered in time are solved.
