Vickers Hardness Tester

Versatile macro-load range for HV/HK scales from 300gf to 30kgf

By selecting between 9 loads steps for macro-hardness testing in Vickers or Knoop, any specimen can be tested and measured within the applicable standards. Fast and easy setting of loads by touch screen monitor menu icon.

Magnification range

Combining the excellent performance of the digital camera, LED illumination and software with a series of available objectives, the DUROLINE V Series provide correct measurement under any test load within the international standards.

'N-Sure' Test and Measurement Software

The 'N-Sure' software program features a flexible Windows based user interface that increases productivity and operator efficiency by automating the test & measurement process and optional motor-stage navigation process. Since the application and removal of the test loads and measurement are fully automatic, repeatability is excellent, testing time is reduced and throughput is increased. As a result, costly and time-consuming rework is eliminated.

For high-volume mounted sample testing, multi-sample mount holders are available to further increase the productivity and throughput of samples.

The easy-to-operate test & measurement program, clear images captured by integrated camera and high-resolution display on 22" touch screen monitor provide the lab staff easy access and shared visibility of indent results to analyse and discuss together. Operators are guided by the user-friendly program logic combined with quick system settings such as fast and easy setting of loads by touch screen monitor menu icon. Vickers or Knoop hardness values are automatically generated on screen by use of the standard provided Auto-measurement function.

Automatic Light Brightness

The light brightness is automatically adjusted for the best image quality and the most accurate auto measurements.

Automatic Evaluation

Diagonals of indentation are measured automatically and hardness value appear on the screen.

Database generating test results and reports

'N-Sure' software program provides advanced database management of test results, report generation and printing functions. Saving and retrieving measurement data is an absolute requirement when it comes to testing hardness results of critical components in various industrial segments. The N-Sure program ensures that data is safely stored and presented in standard or customized reporting form.

Factory Certificated Direct and Indirect Calibration Report

All DUROLINE V-Series testers are calibrated according to DIN EN ISO 6507-2:2018 Vickers hardness test standard.

Comes with ISO/DaKKs Certificated Vickers Indenter (Made in Germany)

An ISO/DaKKs Certificated Vickers Diamond Indenter is included as standard for all DUROLINE V-Series Hardness Testers.

Case Hardening Depth (CHD) Testing

Case Hardening Depth Module is optionally available for DUROLINE V-series. DUROLINE V-series can be equipped with a Digital Manual XY-Stage that includes one Slyvac digital micrometer and one analogue micrometer. Readings from Slyvac micrometer is transferred to N-Sure software simultaneously. In this way, automatic features of CHD software module can be used.

Case Hardening Depth (CHD) Testing

Scanning Overview Image Feature

Mapping function allows overview image of complete sample surface. The test points are easily determined on the sample with pre-defined or user defined patterns.

Closed-Loop Controlled Load Application by Load Cell Technology

All DUROLINE V-Series testers equipped high technology closed-loop load cell system. Load cell system provides maximum accuracy and repeatability for all test loads without exceeding target load threshold.

High precision spindle

For accurate Vickers hardness testing, the elevating speed and backlash of the spindle are critical. By using quality components and design experience, the DUROLINE V Series spindles guarantee long life without loss of accuracy due to wear and friction, even for large and heavy specimens.

Automatic Light Brightness

The light brightness is automatically adjusted by the user interface software for the best image quality and the most accurate auto measurements. The hardness tester equipped with powerful LED light source and compact optic system to provide excellent image quality.
