The parallel gauge blocks are very precise instruments used to check and calibrate measuring instruments. The blocks are used as 'sample measurements' to ensure that measuring instruments function correctly and produce accurate results. They find application in the manufacturing industry, metrology and calibration laboratories, aerospace, medical, optics and many other fields.
