The Ideal Industries 35 205 torpedo level is a 9 long spirit level that has one level, one plumb, and one 45 vial with a sensitivity of 1mm/m or 30 seconds for determining horizontal and vertical plane as well as incline. The vials are made of acrylic resin to resist breakage. The level is fitted with three rare earth magnets to adhere to metal surfaces and has a V shaped groove along each of the two leveling surfaces that provides reliable seating when leveling round items such as pipe, conduit, and shafts. It has a die cast aluminum body for light weight, durability, and corrosion resistance. 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. Ideal Industries manufactures test and measurement equipment, electrical supplies, and tools, among other products. The company, founded in 1916, is headquartered in Sycamore, IL.
