The Kapro 240 bullseye level is a 1-3/4" diameter spirit level with a circular vial for determining horizontal plane simultaneously in all directions and three mounting holes for attaching to machinery and other equipment. The vial has a center marking for finding level, has a sensitivity of 30 minutes, and is set in a plastic frame for light weight. Levels are used in the building trades, engineering, surveying, and metalworking, among other applications.

Levels are instruments that are used to determine the true horizontal or vertical plane of a surface. The most common type of level is the spirit level, or bubble level. Spirit levels have a liquid-filled, bowed tube (also called a vial) with a bubble that moves when slight adjustments are made to the level. When the bubble settles between marked points on the vial, it indicates that a surface is horizontally or vertically straight. Levels can have one or more vials to determine the horizontal plane, the vertical plane, or various points between, such as a 45-degree angle, simultaneously. Some levels include a laser line indicator that projects a horizontal or vertical beam on a surface. Bullseye levels, or surface levels, are circular, flat-bottomed spirit levels that determine whether a surface plane is level. Machinists’ levels are made of metal and have surfaces designed specifically for rugged use in a machine shop or tool room. Levels can range from highly-complex and accurate machines, such as those used in the surveying and construction industry, to precision instruments used in carpentry and other building trades, to simple, pocket-sized devices for do-it-yourself projects.

Kapro manufactures spirit levels, laser levels, layout tools, and measuring tools. The company, founded in Israel in 1974, meets International Organization of Standardization (ISO) standards 9001, 14001, and SA8000.
