Brinell Hardness Tester - QualiBrineller

Main Tester

• Innovative closed-loop load cell technology
  • Eliminates the need for handling heavy weights or high-maintenance hydraulic load systems
  • Absence of mechanical weights eliminates friction and makes the tester less sensitive to misalignments caused by vibrations
  • Highly accurate measurements within 0.5% for all test loads
  • Eliminates load over/undershoot from traditional open-loop or dead weight systems
  • The overall weight of the machine is approximately 50% less than the traditional dead weight type tester
• Can be supplied with a built-in digital microscope, tablet PC with integrated automatic image analysis software, and/or automated test cycle
• The built-in LCD screen will guide the operator through the selection process of proper Brinell scale for different materials and will inform the operator of what indenter needs to be utilized for the selected Brinell scale.
• Selectable dwell time can be set via the LCD display
• Automatic test cycle
  • Load application, dwelling, and unloading is performed automatically
  • Improves the accuracy and reproducibility of test results by reducing human operator interaction
  • The optional stepper motor can be supplied to automate the lifting and positioning of the test anvil prior to load application, ideal for frequent testing or testing of heavy parts – See the Selection Guide section below for more details

Optional Built-In Brinell Indentation Measuring System - QualiScope

The QualiBrinell QS models are equipped with a built-in Brinell indentation measurement system. The fully automatic image analysis software can be installed on most modern desktop or laptop PCs and offers the following features:

• CCD camera capture the indentation image, and powerful image analysis software measures the size of the indentation and automatically calculates the Brinell hardness value based on the applied load
• Saves valuable operator time and increases accuracy compared to the traditional use of an optical microscope
• USB connection to PC and supports Windows
• Conversion to other hardness scales according to ASTM E140
• A large number of results can be stored including the image from each test and descriptive information about each sample
• Data can be exported to Excel or other software for further analysis
• Can perform measurements for all test loads between 62.5 kgf and 3000 kgf, for indenters 2.5 mm, 5 mm, and 10mm, and for Brinell hardness values between 3.18 HBW and 658 HBW

Advantages

• Greatly simplifies the indentation and measurement process, allowing for more accurate results more quickly than traditional testers
• Can eliminate the need for separate microscope and PC
• Market leading price-performance ratio
