Support Ring for Curved Surfaces

The Sauter HO-A07 support ring is designed for use with the HO series UCI hardness testers. It enables more stable and accurate hardness testing on cylindrical or curved surfaces, especially shafts and pipes.

By creating a uniform contact surface between the UCI probe and the test object, the support ring helps reduce measurement variability and improves repeatability—ideal for industrial and on-site metal hardness testing where precision is critical.

Key Features

• Application-specific design: Enables stable positioning of the HO probe on curved surfaces
• Improved accuracy: Minimises errors caused by uneven contact or probe tilt
• Compatible with: All models in the Sauter HO UCI hardness tester range
• Use case: Recommended for pipes, rods, and cylindrical components
