Fowler 54-422-444-0, Xtra-Value Digi-Level Digital Protractor,Blue/Black
The Fowler 54-422-444 Xtra-Value Digi-Level is a digital level for determining the degree of incline at any angle through 360° (4 x 90°) with a resolution of 0.05° and an accuracy of + or - 0.2° for precise readings, and features a zero function that can be set to read absolute zero for determining horizontal plane. The zero function can also be set at any angle to measure the relative angle between two surfaces. The level has an LCD and a hold function for freezing readings on the display. It is housed in aluminum for light weight and corrosion resistance. It operates on a single 9V battery (included), weighs 1.1 lb., and measures 3 x 4 x 1 inches (H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back). 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.
The Fred V. Fowler Company manufactures inspection and measurement instruments such as electronic indicators, calipers, bore gages, and digital scales. The company, founded in 1946, is headquartered in Newton, MA.
