Rockwell hardness tester Qness A+ EVO series

BrinellVickersKnoop/Vickers

Introduction
The A and A+ variants of the Qness 250 / Qness 750 / Qness 3000 EVO series are fully automated macro hardness testers designed for serial and laboratory workflows. Fully automated 3‑axis control enables testing of specimens with varying test heights. The Z axis asynchronous motor delivers clamping forces up to 3,200 kg for secure fixation of heavy parts.

Product advantages

• Precision test head control via asynchronous motor
• Automatic XYZ test progression for different sample heights
• Base cabinet and safety features fully integrated into machine design
• Fix or swivelling downholder options for maximum clamping safety
• High-quality image acquisition with industrial CMOS cameras
• Qpix Control2 software with intuitive 3D control elements
• A+ variant only: sample overview camera with automatic image capture

XLED Brinell evaluation lenses
XLED illumination modules improve Brinell indentation analysis. Direct, wide-area illumination from XLED lenses ensures precise and repeatable indentation imaging and measurement independent of material and hardness, avoiding artifacts common with standard objectives.

Optics & camera
The EVO series uses a universal microscope system covering visual ranges from 0.1 mm to 8 mm with uniform illumination and high contrast without dark edges. Industrial 5‑megapixel Ethernet colour cameras (CMOS) provide stable transmission and enable remote PC setup at distance from the tester.

Test methods & force range
The system supports Brinell, Vickers, Rockwell and Knoop methods as well as plastics testing. Test force ranges by model: Model 250 A+: 1–250 kg (9.81–2450 N); Model 750 A+: 0.3–750 kg (2.94–7358 N); Model 3000 A+: 0.3–3000 kg (2.94–29430 N). Integrated conversions comply with DIN EN ISO 18265, DIN EN ISO 50150 and ASTM E140.

Automation & handling
Fully automatic, robust motorized XY slide with high-precision positioning drive and dynamic joystick control for all three axes. Usable motorized support surface 450 x 300 mm. Innovative 8‑position tool changer (rotational step 15°) stores up to 8 tools to reduce changeover times.

Height handling, clamping & safety
Z height for each XY test point can be individually selected and automatically adapted between specimens of different heights. CAS (Collision Avoiding System) uses predictive 3D motion calculations to protect mechanical parts. Patented workpiece recognition reduces approach speed automatically. A/A+ versions feature a high-performance induction motor enabling clamping forces up to 3,200 kg; fix or motorised swivelling downholder options support different test methods (e.g. Rockwell, Brinell).

Special functions

• Sample image camera (A+): records table overview images for documentation and protocols
• Edge recognition: automatic adaptation of test row start points to sample edges for higher automation in serial testing
• Swivelling test-piece support: allows testing when test surface is not parallel to support
• Specialised holders/modules available (Jominy, tube testing, automated norm-compliant cycles)

Software & connectivity
Qpix Control2 offers an intuitive PC interface with 3D-oriented controls: automatic height adjustment, contactless exploration, CAD import and extensive test program management. Qpix Control2 integrates into the Verder Scientific IoT platform for remote monitoring, live notifications, backups and automatic updates. Qconnect enables inter-device connectivity and supports REPORT, PDF, XML, CSV, Q‑DAS, IOT, LIMS, OPC UA and ERP integrations.
