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.
- Manual Load Control: Load is applied by hand via a handwheel, giving the user direct control over force application.
- High Resolution: Readings displayed to 0.1 HR for fine-grained hardness measurement.
- Statistical Data Functions: The display can show average, maximum, and minimum hardness values over multiple tests.
- Scale Conversion: Converts Rockwell results to Vickers (HV), Brinell (HB), and tensile strength, making cross-scale comparisons easier.
- Standards Compliance: Built to meet ISO 6508 and ASTM E18 Rockwell testing standards.
-
Workpiece Size Requirements:
- Flat surfaces: length > 190 mm, width > 60 mm, thickness > 5 mm.
- Cylindrical / tubular parts: length > 200 mm, diameter > Ø50 mm, wall thickness > 8 mm.
- Power Supply: Uses 3 × AAA batteries, making it convenient and portable without cabling.
- Compact & Portable: Dimensions of approximately 245 × 105 × 230 mm, and a weight of 5.3 kg, giving good stability while remaining manageable for transport.
