Digital Rockwell hardness testing systems designed for accurate quality and process control with stable performance, precise measurement and intuitive touch-screen operation.
High measurement accuracy, automatic test-force control, integrated data analysis, hardness conversion and built-in printing.
Durable & Precise Rockwell Hardness Testing
Rocknix170 and Rocknix400 are designed to meet demanding industrial quality-control and research requirements where durability, stability and precise generation of critical hardness-test data are required.
High-Accuracy Measurement
A built-in measuring device provides high measurement accuracy for reliable Rockwell hardness testing.
Repeatability & Reproducibility
The system is designed to provide optimum repeatability and reproducibility across repeated hardness measurements.
Responsive Touch Screen
Black crystal touch-screen buttons are designed for long service life, while the ultra-sensitive touch screen provides timely response.
Dynamic Test Display
The testing process, hardness values and data statistics are dynamically displayed for clear and intuitive monitoring.
Brake System
The Rocknix170 / Rocknix400 incorporates an automatic brake system for initial test-force loading, supporting controlled and consistent hardness testing operation.
Applications
Suitable for Rockwell hardness testing of quenched, tempered and annealed materials, cold hard castings, malleable castings, cemented carbide steel, aluminium alloy, copper alloy, bearing steel and other applicable materials.
System Features
Motor-Controlled Test Force
Test-force loading, holding and unloading are controlled by motor to reduce operating error and improve test consistency.
Built-In Printer
An integrated printer allows test data and results to be printed directly from the hardness tester.
Hardness Distribution Analysis
Single-point and multi-point modes are built in. Multi-point mode provides hardness distribution curve analysis and automatically calculates maximum, minimum and average values.
Automatic Hardness Conversion
The system integrates ASTM-E140-12be, ISO-18265-2013 and GB/T1172 hardness conversion standards for automatic conversion without manually checking comparison tables.
Hardness Limit Alarm
Upper and lower hardness limits can be configured. The system displays an indication window to show whether the measured result is within the specified limits.
12-Language Interface
The interface supports Simplified Chinese, Traditional Chinese, English, French, German, Russian, Portuguese, Spanish, Korean, Japanese, Italian and Thai.
15 Measuring Scales
Fifteen measuring scales can be independently modified to support different Rockwell hardness testing requirements.
Integrated Data Processing
A user-friendly interface and integrated data processing are supported by a dual-core 32-bit ARM processor.
