    Precision Levels

    Image of Product. Front orientation. Levels. Precision Levels.
    A favorite among machinists setting up and inspecting lathes and other CNC machines. These levels include a highly sensitive vial made from ground glass for a precise shape and clear view. Their heavy cast iron base keeps them stable on surfaces, so they can detect even miniscule tilts and misalignments that a standard level can’t. The bottom of their base also has a V-shaped indentation, so you can rest them on flat and curved surfaces alike.
    Levels with Calibration Certificate—When precision readings are required for quality control or by regulation, use a level that includes a calibration certificate traceable to NIST. The certificate states that the level has passed a test for accuracy, so you can be confident your readings are correct and consistent.
    Starrett—These levels are machined in the U.S. by Starrett, one of the most trusted names in precision measuring tools.

    Two-Axis Precision Levels

    Level horizontal surfaces in two directions at the same time with the highest degree of accuracy. The highly sensitive glass vials on these levels sit perpendicular to one another – place them on the corner of platforms and surface plates to check if they’re tilting sideways, forwards, or backwards.
    Levels with Calibration Certificate—When precision readings are required for quality control or by regulation, use a level that includes a calibration certificate traceable to NIST. The certificate states that the level has passed a test for accuracy, so you can be confident your readings are correct and consistent.
    Cast Iron Base—Heavy cast iron keeps your level stable on surfaces and won't contract or expand in extreme temperatures.
