About Starrett 98Z-12TCAL Precision Machinists' Level In
The Starrett 98Z-12 precision machinists’ level is a 12" 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, a cross-test vial that enables simultaneous levelling in two directions, and a plumb vial for determining vertical plane. The main vial is adjustable to a positive setting for accurate results, is made of ground glass that resists scratching to provide clear readings, and is housed in a brass tube with a friction-fit closing to resist breakage. A V-shaped groove along the base provides reliable seating when levelling round items such as pipe, conduit, and shafts. The level has a cast iron base for durability and it comes with a finished wood storage case. 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.
