Supports multiple hardness units: Measure common hardness values ​​such as HV, HB, HRC, HRB, HRA, and HS. Suitable for a variety of workpiece surfaces: Suitable for testing grooves, thin parts, hardened layers, and high-hardness materials. Suitable for large castings and forgings: Measure rough or heavy workpieces, enabling rapid on-site hardness assessment. Supports bracket measurement: Lightweight samples can be measured directly, while heavy workpieces require close coupling. Small indentation, high precision: Utilizing the rebound principle, the indentation is minimal, without damaging the workpiece surface., Manufacturer: ZXZZAS
