Manufacture High-Quality, Customizable Plastic Or Acrylic (PMMA) Round Bubble Level Vials At A Low Price By Aohong Co.

Round level vials, also known as circular level vials, are spirit levels utilized to determine the levelness of a surface, distinguished by their circular or dome-like shape and consisting of a slightly concave surface filled with liquid and a bubble. Constructed from plastic, glass, or metal, these vials are chosen for their durability, cost-effectiveness, and precision, catering to varied applications and environments across numerous industries, such as construction and carpentry, where precise horizontal alignment is vital.

Angular value

The accuracy of a bubble level vial, or its angular value, pertains to the inclination of the bubble during movement. For round level vials, accuracy is defined by the bubble’s inclination as it moves 2mm from the center along any radial direction. In contrast, for elongated bubble vials, accuracy refers to the bubble’s inclination when it shifts 2mm along the axial direction.
