Mitutoyo 613681-805-01B Gauge Blocks are metric gauge blocks with a calibrated coefficient of thermal expansion. They are available in various sizes from 100 to 500mm

They offer you the following benefits:

• Mitutoyo offers top-level gauge blocks (steel and ceramic) which are superior to K-class blocks, with their quality supported by Mitutoyo€˜s best technologies.
• They feature an accurately calibrated thermal expansion coefficient measured with a proprietary double-faced interferometer (DFI).
• Each gauge block is calibrated for length on a highly accurate gauge block interferometer (GBI) system.
• Uncertainty of thermal expansion coefficient: 0.035 x 10-6 /K (k=2).
• Uncertainty of length measurement: 30 nm (k=2), for 100mm blocks.
