Ceramic Square Ruler made by Al2O3
Ceramic Square Ruler made by Al2O3 with six precision surfaces according to DIN Standard. The flatness, straightness, perpendicular and parallelism can reach 0.001mm. Ceramic Square has better physical properties, which can keep high precision for long time, good wear resistance and lighter weight. Ceramic Measuring is advanced measuring so its price is higher than granite measuring and metal measuring instrument.
