Wilson Hardness Testers — Rockwell, Vickers, Knoop & Universal
Buehler engineers , manufactures, and supports all Wilson hardness testers. Every Wilson hardness tester is engineered for industry-leading Gauge Repeatability and Reproducibility (GR&R), ensuring your hardness testing results are accurate, consistent, and audit-ready. Paired with DiaMet software and certified Wilson test blocks, JH Technologies provides a complete hardness testing solution — from equipment to calibration standards and support.
Rockwell Hardness Testers — Wilson 574 & RH2150
The Wilson Rockwell series is the benchmark for Rockwell hardness testing in production and quality control environments. Conforming to ASTM E18 and ISO 6508, these Rockwell hardness testers are trusted across aerospace, automotive, and metals manufacturing for their speed, reliability, and exceptional GR&R performance.
Wilson Rockwell 574
- Best-in-class GR&R: Gold standard in Rockwell hardness testers
- Load range: 3–150 kgf | Available as Regular (574R) or Twin Scale — Regular + Superficial
- High-precision depth measurement: Auto preload brake ensures consistent, repeatable indentation
- Standards: ASTM E18, ISO 6508
- Output: Built-in USB port for fast data transfer directly to Excel
Wilson RH2150
• Flexibility: Wide testing range 1–187.5 kgf across multiple Rockwell scales
• Two sizes: 10-inch and 14-inch vertical capacity to accommodate different part geometries
• Ergonomic design: Fast data output and intuitive interface for high-throughput environments
• Software: Optional DiaMet integration for automated test cycles and reporting
Vickers & Knoop Hardness Testers — Wilson VH Series
The Wilson VH series delivers precise Vickers and Knoop hardness testing for materials that require high-accuracy microhardness measurement. Whether you need a microhardness Vickers tester for thin coatings, case-hardened parts, or weld HAZ analysis — or a macro-Vickers system for bulk materials — the VH range covers it all.
Wilson VH3100 — Microhardness Tester
- Type: Dedicated microhardness Vickers tester for thin films, coatings, and small components
- Load range: 05–10 kgf | 3-position virtual turret with fixed indenter and objectives
- Automation: DiaMet software provides automatic test and measurement indentations
- Best for: Thin film analysis, electroplating, weld HAZ, case depth measurement
- Standards: ASTM E384, ISO 6507
Wilson VH3300 — Fully Automated Vickers Hardness Tester
- Type: Fully automated Vickers and Knoop hardness tester — macro and micro
- Load range: 10 gf to 50 kgf | 6-position turret with 3-indenter design
- Speed: Auto-focus and auto-measurement in under 5 seconds
- Automation: Programmed test sequences, collision-resistant system, optional overview camera
- Software: DiaMet software for automated cycles, report generation, and hardness mapping
- Standards: ASTM E384, E92, ISO 6507, 4545
Universal Hardness Tester — Wilson UH4000 Series
The Wilson UH4000 is a true universal hardness tester — a single machine that performs Vickers, Knoop, Rockwell, and Brinell hardness testing across load ranges up to 3,000 kgf. Ideal for labs that test a wide variety of materials and need one hardness testing machine for all major scales.
- Three configurations: UH4750 | UH4250 | Auto UH4250 (motorized XY stage for automated traverses)
- Standards: ISO 6506, 6507, 6508, 4545 and ASTM E18, E10, E92
- Software: DiaMet software for automated testing, reporting, and multi-method hardness mapping
- Best for: High-volume labs, R&D facilities, and labs that test plastics, ceramics, and metals
Key Benefits — Wilson Hardness Testers
- Industry-leading GR&R: Wilson testers consistently deliver the best GR&R in independent studies
- Collision-resistant system: Prevents indenter or objective damage during automated testing — reduces costly repairs
- Minimized complexity: Fixed alignment of indenters, objectives, and optional overview camera reduces moving parts and service requirements
- DiaMet software: Purpose-built hardness testing software for automated cycles, weld testing, case depth analysis, and full report generation
- Designed for standards: All testers conform to relevant ASTM and ISO hardness testing standards
- Optional clamping tool: Adds stability for difficult-to-hold parts throughout the testing process

Choosing the right hardness testing method is one of the most important decisions in materials quality control. Rockwell, Vickers, and Brinell are the three most widely used hardness tests in industrial and research labs — but they work differently, suit different materials, and give results on different scales.
Our team can guide you through product selection, pricing, and available configurations based on your specific application needs. We also offer live demos and promotional pricing on select demo units.
