INSIZE ISHR-D121 Digital Magnetic Rockwell Hardness Tester
Are you looking for a powerful and portable digital magnetic Rockwell hardness tester, engineered for measuring the surface hardness of large, heavy steel or iron workpieces? Thanks to its magnetic base, The INSIZE ISHR-D121 can securely clamp onto ferrous parts, enabling stable testing without the need to move or reposition cumbersome components. With digital readout, statistical functions, and scale conversions, it's ideal for in-shop quality control, field inspections, and production environments that demand reliable, repeatable Rockwell hardness measurements.
Key Features
- Magnetic Clamping Base: Two magnetic chucks affix firmly to ferrous workpieces for stable testing on large or heavy parts.
- Digital Depth Measurement: Uses a depth sensor with micro-processor to measure indentation depth precisely and compute hardness automatically.
- Scales Supported: Rockwell scales HRA, HRB, and HRC.
- Test Force Options: Pre-load of 10 kgf, with selectable major test forces of 60 kgf, 100 kgf, and 150 kgf.
