Digital / Micro Auto Turret Vickers Hardness Testing Machine With
Automatically Loading Method
Brief Introduction
It has a more faster testing speed than other ordinary Micro
hardness tester. The hardness value can
be displayed directly and not need to enter the length of the
diagonal. And the HVD 1000AP is famous
as its fashion and decent design, high testing precision, stable
functions and simple operation.
Main Functions and Features
1. Special designed for improving the working efficiency of our
customers as its automatically design.
After adjusting the focal length, the objective lens and indenter
can be switched automatically. And the
testing force can load, dwell and unload automatically. Then the
objective lens will automatically return
to the initial focus state, and the length of indentation can be
measured directly.
2.The independent research and development of lifting system and
positioning system, ensured the accuracy and repeatedly of the
testing process.
3. The optical system designed by senior optical engineer (who
worked in the Shanghai Optics And
Fine Mechanics Institute, Chinese Academy of Science) not only meet
the definition of hardness
testing requirements, but also can observe the microstructure of
the material.
4.With Vickers hardness and Knoop hardness testing capabilities,
and testing force can be extended
to 2KG.
5. Testing method, testing power and duration time can be displayed
directly on the LCD screen.
6. According to different visual habits of the operators, the
strength of the light source can be adjusted. To avoid the visual
fatigue for long time operation.
7. The testing data able to be printed directly by the built-in
printer.
8.Reserved image channel,can be connected with computer, used the
image analysis software to analyzing the physical and chemical
properties of the material.
Main Purpose and The Scope of The Application
1. Testing the hardness of metallographic structure, from the most
soft material to the most hard material.
2. Carburizing, nitriding, hardened layer, surface coating, steel,
nonferrous metals.
3. The hardness of the glass, ceramic materials.
