The Starrett 98-8 precision machinists’ level is an 8″ long spirit level with a graduated main vial that has a sensitivity of 0.42 mm/m or 80 to 90 seconds for determining horizontal plane and a cross-test vial that allows simultaneous leveling in two directions. The primary vial is adjustable to a positive setting for accurate results, is manufactured from ground glass that resists scratching to supply clear readings, and is housed in a brass tube with a friction-are compatible closing to withstand breakage. A V-shaped groove along the bottom provides reliable seating when leveling round items such as pipe, conduit, and shafts. The extent has a Cast-iron base for sturdiness. Levels are used within the building trades, engineering, surveying, and metalworking, among other applications.

Levels are instruments which might be used to decide the actual horizontal or vertical plane of a surface. The commonest form of level is the spirit level, or bubble level. Spirit levels have a liquid-filled, bowed tube (often known as a vial) with a bubble that moves when slight adjustments are made to The extent. When the bubble settles between marked points at the vial, it indicates that a surface is horizontally or vertically straight. Levels will have a number of vials to decide the horizontal plane, the vertical plane, or quite a lot of points between, such as a forty five-degree angle, concurrently. 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 decide whether a surface plane is level. Machinists’ levels are manufactured from metal and have surfaces designed in particular for rugged use in a machine shop or tool room. Levels can range from highly-complex and accurate machines, such as the ones used within the surveying and construction industry, to precision instruments utilized in carpentry and other building trades, to simple, pocket-sized devices for do-it-yourself projects.

The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The corporate, founded in 1880, is headquartered in Athol, MA.
