Gage Blocks
Rectangular Gage Block wit CTE Gage Blocks with Thermal Expansion Coefficient Data
• Mitutoyo offers top-level gage blocks (steel and ceramic) which are superior to K class blocks.
• Comes with a highly accurate thermal expansion coefficient measured with a high- accuracy double-faced interferometer (DFI). • The high-accuracy gage block interferometer (GBI) guarantees high dimensional accuracy. • Mitutoyo offers rectangular gage blocks, having nominal values from 100 to 500mm Grade: K class in ASME Uncertainty of thermal expansion coefficient: 0.035 x 10 -6 /K (k = 2) Uncertainty of dimension measurement: 30nm (k = 2), for 100mm block

ZERO CERA Blocks
• Thermal expansion in the temperature range 20±1ºC less than 1/500 that of steel (0±0.02×10 -6 /K(20ºC)) • Almost no secular change both in dimension and coefficient of thermal expansion
• Complementary ultra-low thermal expansion and high specific rigidity (Young's Modulus/specific gravity)
