Circumference Ruler Stainless Steel Outside Diameter Ruler

1.A vernier gauge is a precision measuring tool specifically designed for measuring the circumference and diameter of circular workpieces. It features a curved body and uses the vernier scale in conjunction with the main scale to achieve highly accurate readings. Compared to conventional rulers or calipers, a vernier gauge is more convenient for measuring pipes, round bars, and shafts, offering intuitive readings and a wider measuring range. It is widely used in industries such as machining, metallurgy, petroleum, chemical engineering, and pipe manufacturing.

2.To use a vernier circumference gauge, the operator simply wraps the curved gauge around the perimeter of the workpiece being measured and directly reads the circumference. It is widely used in pipeline manufacturing, round steel inspection, and mechanical maintenance, and is particularly suitable for rapid inspection of large-diameter circular workpieces. With its efficiency, accuracy, and durability, the vernier circumference gauge has become an indispensable measuring tool in factory quality inspection, scientific research, and engineering construction.
