The Empire 205mm Billet Torpedo Level is our strongest torpedo level, starting life as a single piece of Billet Aluminium. True Blue vials are ground, drilled, and machined using Empire's most advanced manufacturing processes. True Blue vials darken the outer edge of the vial bubble to ensure accurate reading in all lighting conditions and deliver best-in-class accuracy. Coupled with anodised aluminium, this billet level delivers unparalleled strength and durability. A Vari Pitch vial is used to measure fall over distance. This level shows the millimeter per meter fall, up to 40mm, over a horizontal distance using the bubble in the Vari-Pitch vial. Vials display angles of 0, 45 and 90 and mm fall per meter to 40mm V-groove for pipe and conduit work.
