Evocus Automatic Full Scale Rockwell Hardness Tester (RocknixDual Series)
Full-scale Rockwell hardness testing with 30 Rockwell hardness scales, covering ordinary Rockwell and superficial Rockwell testing.
Automatic loading, holding and unloading of test force with intelligent testing, data analysis and connectivity functions.
Full Scale Rockwell Hardness Testing
The RocknixDual series provides 15 ordinary Rockwell hardness scales and 15 superficial Rockwell hardness scales, supporting a broad range of hardness testing requirements.
The range includes two configurations:
- Auto-RocknixDual – Automatic Full Scale Rockwell Hardness Tester.
- RocknixDual – Digital Display Full Scale Rockwell Hardness Tester.
Connectivity & Interface
8-Inch Touch Screen
Large touch-screen interface for operation, testing and result display.
Built-In Bluetooth
Supports wireless test-data transfer and connection to a compatible Bluetooth printer.
Online Network Port
Ethernet connectivity supports network and cloud-based hardness data applications.
RS-232 Socket
Provides an additional interface for data communication.
USB Socket
Integrated USB connectivity for convenient data handling.
Printing
Supports a built-in printer and an optional Bluetooth wireless printer.
Key Functions
Fully Automated Testing
With one-click start, the workbench automatically rises to the appropriate position and begins testing. After completion, the workbench automatically drops by a preset customizable distance for quick point changes.
Two Workbench Lifting Methods
Supports hand-wheel lifting and electric lifting. The hand wheel directly raises or lowers the worktable, while electric lifting is controlled using the adjustment knob.
Infinitely Variable Speed Workbench Lifting
The side control knob provides stepless manual control of workbench movement. A greater knob rotation angle increases the lifting speed.
Set Hardness Test Range
Upper and lower hardness limits can be defined according to workpiece requirements. Test results can then indicate whether the measured hardness is qualified or outside the specified range.
Loading Process Time Monitoring
If a test workpiece is absent or the start control is activated accidentally, empty loading will time out and automatically stop to help protect the equipment.
Trigger Progress Indicator Bar
During manual operation, a progress bar appears when the workpiece contacts the indenter, helping the operator avoid errors caused by excessively raising the workpiece.
Three Hardness Conversion Standards
Built-in national, European and American hardness conversion standards allow the required standard and scale to be selected, with converted hardness values displayed together with test results.
Multi-Point Testing Data Analysis
Real-time analysis includes the number of tests, highest value, lowest value, average value and standard deviation for a group of measurements.
Multi-Point Test Line Chart
Multi-point test curves are displayed in real time. Hardness limits can be set to make out-of-range points easier to identify.
Internet Connectivity
The hardness tester can connect to a cloud server through Ethernet for remote sharing of hardness test data, historical data tracing and process monitoring.
Real-Time & Historical Data Upload
Test data can be transferred to a mobile phone through Bluetooth or to a computer through a network cable, either by individual test point or test group.
Test Data Printing
Test results can be printed through the built-in printer or Bluetooth printer, or transferred to a computer for printing.
