Small load hardness tester HP30

The HP30 small load hardness tester is designed for automatic and standard-compliant hardness testing according to Vickers, Brinell and Knoop. It covers a load level range from 0.005 to 62.5 kg and can be equipped with various software and image evaluation systems. This enables it to be expanded into a fully automatic testing system.

Precise force application & mechanics

• High-precision, load-controlled force application through closed control loop
• Continuous force monitoring to ensure precise test results
• Individually adjustable load application, holding and removal times
• Optics and test load range are freely configurable

Technical data

• Load capacity up to 120 kg, suitable for heavy test specimens
• Maximum specimen depth: 170 mm, test area height: 245 mm (170 mm with cross table)
• Compact dimensions: 675 × 305 × 674 mm
• Weight: 61 kg (71 kg with cross table)
• Ergonomic design for comfortable operation

Precise imaging and optics

• High-resolution 5 megapixel USB camera for excellent image quality even at high magnifications
• Optical zoom (7x in 10 steps) & digital zoom (4x) allow magnifications from 285x to 2000x 
• Second b/w overview camera (5 MP) with large single image (40×50 mm)
• Infinitely variable LED lighting for optimum lighting conditions and attention to detail
• Automatic indentation measurement (optional) for efficient test sequences
• Automatic 2-fold swivel device (HP 30S) & 6-fold turret (HP 30SR) for quick change between lens and indenter

Automated test sequences & ease of use

• Motorized XY cross table with travel 160 × 180 mm (optionally up to 300 × 160 mm)
• Fully automatic testing of different specimen heights
• Hardness evaluation via HardWin XL software
• Mapping option: two-dimensional or three-dimensional representation of the hardness curve over the entire specimen
• Contour scan with the microscope camera: capture of the specimen edge using composite individual images
• Area scan with the overview camera: Complete capture of the sample using high-resolution image composition

Advanced test methods & analysis functions

• Devices support hardness value conversion in accordance with DIN EN ISO 18265
• Possibility of substitute or control measurement of hardness values:
  • On the saved image
  • On the live image
  • With new impression
  • Quick access to archived test jobs within the software
• Mechanical material testing in accordance with DIN SPEC 4864 including determination of the plastic yield curve & comparative yield strength Rp0.2 from test indentations
• Weld seam testing: processing of individual test samples of the specimen with contour tool, circle tool and splitter tool

Conclusion

The HP30 small load hardness tester impresses with its high precision, flexible customization options and user-friendly automation. It is a powerful instrument for demanding hardness tests and detailed material analyses
