The Set A kit for hardness testers is a comprehensive and versatile solution designed to perform precise hardness tests using various types of indents and anvils. This kit includes a 60 mm flat anvil and a 37 mm anvil with a central projection, allowing proper load application during tests. Additionally, it contains two "V" anvils, one large and one small, perfect for positioning materials with unique shapes.

For Rockwell tests, the kit includes a diamond cone penetrator with a 120° angle and a tungsten carbide ball penetrator with a diameter of 1/16". For Brinell tests, tungsten carbide ball penetrators with diameters of 1 mm (for DIGI RS), 2.5 mm, and 5 mm are included, compatible with DIGI R, DIGI U, and COMP 25 hardness testers. This enables precise measurements on a wide range of materials and hardness scales.

The kit also contains a reference specimen for the HRC and HRBW scales, ensuring proper calibration of the tools, along with detailed user instructions and service keys for optimal system maintenance and use. With these components, the Corredo A kit is an essential complement to hardness testers, enhancing their versatility and accuracy in hardness testing for laboratories and industrial environments.
