Granite surface plates from ULTRA Germany represent high precision and dimensional stability for industrial metrology applications. Manufactured from finest natural hard stone with a homogeneous structure, they comply with DIN 876 and are suitable for use in metrology rooms, production areas and testing laboratories. The measuring surfaces are diamond-lapped, ensuring excellent flatness, long-term wear resistance and a surface that is corrosion- and acid-resistant. Due to the high thermal stability and rigidity of the natural granite material, the surface plates provide reliable measurement conditions even in demanding industrial environments. Final machining is carried out in a climate-controlled environment with constant temperature and humidity. Each surface plate is inspected using calibrated measuring equipment to ensure traceability to national and international calibration laboratories. Delivery includes a calibration certificate. Depending on application requirements, granite surface plates are available in Grade 000 and Grade 00 for highest accuracy in metrology rooms and Grade 0 for high-precision use in production environments. The plates can be supplied with a cabinet base including drawer units or with a robust steel stand. Height-adjustable feet, anti-tip protection and rigid constructions ensure safe and ergonomic operation. Granite surface plates from ULTRA Germany provide a reliable foundation for precision measurement, quality assurance and industrial inspection processes.
