Vickers & Knoop Hardness Testers
DUROLINE M Series are ideal instruments for quality assurance, quality control, research and metallurgical departments to monitor the hardness during fabrication and after heat treatment or welding as well as for the performance analysis on metal parts and new alloys. Typical applications are determining the Vickers microhardness of small precision parts, thin material or wire, coatings and performing case depth determinations (CHD, EHT, NHT) on cross sections, both manually or automatic on this advanced hardness tester system.
Recently developed by an international multi-disciplinary team with a wide hardness testing experience, the DUROLINE M-Series are based on the latest technology available, focused on fast cycle time with high reproduceable accuracy within international standards. The system features a smart and very service-friendly synergy of a robust and proven mechanical construction and integrated electronics system control featured by a fast CANBUS technology and a high-quality Windows based mini-pc. Monitoring the hardness testing process significantly improved by using modern user interfacing technology such as 10-point multi-touch screen operation supported by a fast & secure display connection. Combined with top quality components and a high performance mini-pc, this system guarantees customers a solid and accurate performance over many years to come. In this way, the DUROLINE M Micro-Vickers hardness tester offers a highly functional and reliable automated indentation test & measurement system.
Complete micro-load range for HV/HK scales from 10gf to 1kgf
By selecting between 8 loads steps for microhardness testing in Vickers or Knoop, any specimen can be tested and measured within the applicable standards. Fast and easy setting of loads by a conventional manual knob.
Magnification range
Combining the excellent performance of the digital camera, LED illumination and software with a series of available objectives, the DUROLINE M Series provide correct measurement under any test load within the international standards.
High precision spindle with motorized option
For accurate microhardness testing and fast auto-focusing, the elevating speed and backlash of the spindle are critical. By using quality components and design experience, the DUROLINE M Series spindles guarantee long life without loss of accuracy due to wear and friction, even for automated Z-axis systems.
'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.
Fully Automatic Test and Measurement
DUROLINE M4 is equipped with a high precision motorized XY-stage with 100x150 mm travel range and Autostage software module. It provides multiple tests & measurements fully automatically without operator intervention.
Case Hardening Depth (CHD) Testing
Case Hardening Depth Module is optionally available for all DUROLINE M models. For DUROLINE M1 and M2 models, Case Hardening Depth testing is done manually by digital manual XY-Stage. For DUROLINE M4, Case Hardening Depth testing is done automatically by motorized XY-Stage.
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.
Automatic Focus
(Available on M2 and M4 models) DUROLINE M2 and M4 models are equipped with high precision motorized spindle and Autofocus software module. It automatically sharpens the image in seconds. This provides extra convenience, maximum automation and time saving.
Motorized XY-Stage
(Available on M4 model) DUROLINE M4 is equipped with high precision motorized XY-stage with 100x150 mm travel range and Autostage software module. It provides multiple tests & measurements fully automatically without operator intervention. Mapping function allows overview image of comple sample surface. The test points are easily determined on the sample with pre-defined or user defined patterns.
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.
