Rockwell Hardness Tester Range for Manufacturing and Quality Labs
Measure hardness of metals and engineered plastics with regular and superficial scales in compliance with ASTM E18 and ISO 6508. Select digital or automated models with stable force application for quality control, heat‑treatment checks, and production inspection.
Choose the Right Model
Digital models with software
A digital Rockwell tester provides a high‑resolution display, direct scale selection (HRA, HRB, HRC, plus superficial), guided workflows, conversions, and data export. Built‑in statistics and pass/fail limits support consistent, traceable reports.
Automatic models for throughput
An automatic unit uses motorized loading/unloading and a programmable dwell cycle to increase speed. Closed‑loop force control and automated positioning limit operator influence in busy labs.
Superficial models for thin parts
For thin sections or surface‑hardened layers, a superficial model applies 15/30/45 kgf to protect the substrate. Use HR15N/HR15T or HR30N/HR30T with fixtures that help maintain alignment and edge distance.
Standards and Methods
- Regular scales (HRA/HRB/HRC) use 60/100/150 kgf with a diamond cone or carbide ball. The instrument sequences pre‑load, loading, dwell, and unloading per method.
- Superficial scales use lower loads (15/30/45 kgf) for shallow penetration, reducing substrate effects on thin or coated materials.
- Indenters and verification: certified diamond and carbide ball options, traceable test blocks, and documented indirect/direct verification support long‑term accuracy.
Key Features
- Closed‑loop force application for accurate, repeatable results across operators and shifts.
- Rigid frame and precise alignment reduce compliance and support stable readings.
- Intuitive interface streamlines scale selection, dwell setup, conversions, and daily checks.
- Data management with batch statistics, SPC, report templates, and optional LIMS connectivity.
- Safety and uptime: overload protection, ergonomic layout, self‑diagnostics, and modular parts.
Technical Snapshot
- Loads and dwell: regular 60/100/150 kgf; superficial 15/30/45 kgf with programmable dwell and controlled pre‑load.
- Measurement: high resolution and repeatability across regular and superficial scales; optional uncertainty statements.
- Capacity: generous throat depth, adjustable stage, interchangeable anvils and V‑blocks for small fasteners to larger parts.
- Environment: robust enclosure, vibration control, low noise, and long service life for lab or production use.
Typical Applications
- Heat‑treated steels and tools: check case depth behavior and core hardness.
- Automotive/aerospace components: gears, bearings, shafts, and fasteners to meet specification requirements.
- Nonferrous alloys and engineering plastics: use appropriate scales to avoid surface damage.
Accessories and Options
- Anvils, V‑blocks, and specialty fixtures for rounds, flats, and irregular shapes.
- Indenters, traceable test blocks, and verification kits for routine checks.
- Productivity add‑ons: barcode reader, foot switch, label printer, and streamlined export.
Quality, Calibration, and Support
- Delivered with calibration documentation indicating compliance with applicable methods and a recommended verification procedure.
- Professional installation and training; preventive maintenance and lifetime service options.
- ISO 9001 processes and an in‑house calibration lab support consistent build quality and measurement reliability.
- Proven field base with 3000+ units in over 50 countries and 20+ utility model patents.
Customization and Integration
- OEM/ODM for custom fixtures, anvils, languages, and report templates.

- Configurable setups and documentation to address regional standards and audit needs.
Selection Tips and FAQ
Selection guidance: confirm scale coverage, specimen size, throughput, data needs, and verification workflow before purchase.
Q: When should I choose a superficial scale?
A: Use 15/30/45 kgf on thin sections or shallow case layers to reduce substrate influence and avoid surface damage.
Q: How often should I verify the instrument?
A: Follow ASTM E18/ISO 6508 guidance and your quality plan. Perform daily indirect checks with test blocks and periodic direct verification.
Q: Can the system export data to my quality database?
A: Yes. Options include standardized exports and API connectivity to LIMS/MES.
