Focused on solving the pain point of off-site hardness testing that traditional lab equipment cannot address, this portable Rockwell tester boasts a compact, handheld design without sacrificing testing accuracy. Its interchangeable indenter system allows users to switch between HRA, HRB, and HRC testing modes to meet diverse material testing needs. The built-in data storage module saves up to 1000 test records with timestamp and serial number tracking, enabling full traceability for quality control documentation. The USB interface supports seamless data transfer to a computer for report generation, while the low-power consumption design extends battery life to over 80 hours of continuous use. It also includes a self-calibration function and automatic shutoff to preserve battery life and maintain long-term measurement stability.

Dimensions: 210mm x 150mm x 80mm; Net Weight: 1.8kg; Power Supply: 4 AA batteries (included) or 9V DC adapter; Testing Loads: 60kg, 100kg, 150kg (standard configurations); Indenter Types: 120° diamond cone (for HRA/HRC) and 1/16" steel ball (for HRB); Display: Backlit LCD screen with large, easy-to-read digits; Operating Humidity: 30% to 80% RH (non-condensing); Calibration Standard: Included NIST-traceable hardness block; Data Export: Compatible with Windows-based spreadsheet software; Response Time: <3 seconds per test reading.

This portable Rockwell hardness tester is ideal for metal manufacturing plants, automotive component suppliers, scrap metal recycling facilities, and heavy equipment maintenance teams. Typical use cases include verifying the hardness of cast iron parts, checking the heat-treated hardness of bolts and gears, testing the quality of incoming aluminum alloy sheets, and conducting on-site inspections of large industrial machinery components without needing to remove samples for lab testing. It also supports quality control audits for ISO 9001 compliance by generating standardized test reports for client or regulatory review.
