Rounded Measuring Edges (optional)
All Horizontal Spirit Levels and Crank Pin Spirit Levels can be delivered with rounded measuring edges.
The spirit level receives curves on both longitudinal edges with a Radius of 5.0 mm. Thereby the variant receives 6 measuring surfaces: 2 prismatic surfaces, 2 flat surfaces and 2 radii on both outer edges. Therewith the device can be used on arbors, even and concave curved surfaces and on interior sides of tubes. All measuring lines will be grounded simultaneously in one clamp and will be therefore absolutely parallel.
