Application of TT-AVHT Semi-Automatic Vickers Hardness Tester
It is widely used across various industries and research fields where precise hardness measurement is critical, especially on small, thin, or delicate materials.
Features of TT-AVHT Semi-Automatic Vickers Hardness Tester
- Load range: 0.2kgf-62.5kgf
- 6-station automatic turret, 2 indenter stations (optional), 4 objective lens stations (optional)
- The turret self-protection system can tilt 20° in any direction and cooperates with sensor protection to prevent damage caused by accidental collisions.
- 3 megapixel high-definition imaging system
- Extra-large testing space
- Dual channel lighting for test area
- A variety of sample holding fixtures are available and can be customized.
- Self-developed fully automatic hardness testing system
- Optional touch display operation, multi-channel operation mode meets the needs of different application scenarios
- Optional eyepiece mode
- 6-station precision turret and optical system:
Equipped with a 6-station turret as standard, which can install Vickers, Knoop and Brinell (1mm, 2.5mm, 5mm) indenter. AVHT Series has 4 objective lens stations, which can be selected from 2.5X, 5X, 10X, 20X, 50X, according to different configurations. Combined with the use of a high-definition camera with optical zoom, images are presented more clearly
- Z-axis dynamic control and anti-collision protection
The high-end ball-bearing Z-axis screw is a unique technology that enables the Z-axis to achieve micron-level precision displacement while also supporting high-speed autofocus. AVHT Series’ control of the Z-axis can be achieved in a variety of ways, such as test programs and mouse wheels. The Z-axis displacement speed of 0.01-20mm/s makes the positioning of the specimen more convenient and faster. To avoid collision between the workpiece and the turret, the AVHT Series is equipped with a collision detection device and a Z-axis retraction system on the Z-axis, so that neither the hardness tester nor the workpiece will suffer any damage.
- Pattern Editor
Optimizing operating comfort, the software has a range of standard functions such as automatic measurement, autofocus, reporting, test program storage, etc.
- Hardened layer depth test
Conduct standardized CHD/SHD/NHD testing according to standard regulations. The test can be started directly under the microscopic image or under the panoramic image. Additional hardness core points can be set individually for NHD style.
- Auto-focus Measurement
Z-axis high-precision lead screw, high-definition camera, and powerful software algorithm make autofocus fast and accurate
- Report Generator
The test report customization function of the report generator allows users to add company details and companies to the report, and can also layout test results, charts, indentation pictures and other content as needed. All reports can be printed directly via a laser printer (optional) connected to the instrument. Can also output to CSV document
