Two-Axis Precision Levels

Straight | Square |
![]() | |
Triangle |
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.
Granite Base—Granite chips off instead of denting or deforming when dropped. It also won’t corrode in wet environments like cast iron or steel, so the base always stays accurate.
Starrett—These levels are machined in the U.S. by Starrett, one of the most trusted names in precision measuring tools.

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.

Surface-Mount Precision Levels
![]() |
Screw these levels onto CNC machines and other equipment to keep them perfectly level over time. With a highly sensitive glass vial and a heavy steel base for stability against surfaces, they detect even the smallest horizontal tilts and misalignments, so you can correct them before they affect machine performance.
Screw-On Levels—Fasten these levels to any drillable surface for the most secure mount that won't shake loose, even on vibrating equipment. Fasteners are not included.

Mount these levels onto CNC machines and other equipment for repeat horizontal level checks in two directions at the same time. With a highly sensitive glass vial and a heavy cast iron base for stability against surfaces, they detect even the smallest tilts backwards, forwards, or sideways, so you can correct them before they affect machine performance.

Digital Precision Levels
![]() |
You won’t need to choose between precision or convenience with these levels. Their highly sensitive sensor accurately determines level, even when placed on vibrating machinery and equipment. Clearly read the high-contrast display in any lighting conditions – no need to squint to read vials. They stabilize in five seconds after you position them, so you can quickly check the alignment of one part and move on to the next item. You can also view the angle and slope of a surface without a separate tool. When you need to use these levels under machines or in tight spaces between parts, connect them to your smart device via Bluetooth. The free app lets multiple users view readings remotely.
In addition, the V-shaped indentation on the base means you can rest them on flat and curved surfaces alike. These levels also have a false zero setting lets you set any position as a reference point when you need to replicate angles on multiple surfaces.
Granite Base—Granite chips off instead of denting or deforming when dropped. It also won’t corrode in wet environments like cast iron or steel, so the base always stays accurate.
