516-771-60 | ZERO CERA Blocks (Ultra-low Thermal Expansion) | MITUTOYO

• ZERO CERA Blocks are next-generation gauge blocks made of special ceramic materials that have extremely low thermal expansion. They are lightweight, easy to handle, and slow in aging (thermal expansion coefficient: 0±0.02×10-6/ K (20 °C), specific gravity 2.4 kg/cm3). Many research institutions and academic institutions rely on ZERO CERA Blocks in various applications, including the study of methods of calibrating CMM.
• Each block is marked with ”ZERO CERA BLOCK” logo.
• Available in the nominal sizes (30 to 1,000 mm) of rectangular gauge blocks.
