- ZERO CERA Blocks
These are ultra-low expansion ceramic gauge blocks. The ZERO CERA Blocks offer you the following benefits:
- Thermal expansion at 20 ±1°C is less than 1/500 that of steel.
- There is almost no secular change either in the dimension or coefficient of thermal expansion.
- You will find them light and easy to handle.
- They are rust free.
- They are magnetisation free.
