Detailed Product Description
Digital LCD Screen Micro Vickers Hardness Tester MHV-5Z / 10Z / 30Z
/ 50Z
1. The Digital Vickers Hardness Tester is a new type
high-tech product combining the optical, mechanic and electronic
techniques; with a large LCD screen display, a novel and pleasing
appearance, direct-viewing, operational functions and reliability,
hence it is an i
2. The hardness tester is adopted such techniques as a
precise design in the field of mechanics, a higher amplification
objectives and digital micro eyepiece in optics field and cold
light source for measuring light source, etc.
3. Due to adopt the closed-circuits in loading control
system, it makes the accuracy of test force higher, the
repeatability and stability of displaying values better. It is the
initiate of home to adopt this system on Vickers hardness tester.
4. By means of touch keys on the operating board, the dwell
time for test force can be preset, the luminosity of light source
can be regulated, Vickers or Knoop measuring method can be
selected, hardness scales can be exchanged and files can be stored,
etc. All the testing data such as the indentation length, the
hardness value, the number of the measurements, and year, month,
day, and time are all shown on the LCD screen. It can test result
and handle data, and output by printer as well. By means of RS232
interface, the instrument would be connected with computer.
5. According to the particular requirements of the client,
the instrument can be equipped with CCD device to enable the video
measuring and auto image measuring. The instrument is suitable for
testing the micro and thin pieces, the parts with the permeated and
coated surface, it is also fit for testing Vickers hardness value
for the crisp materials such as the agate, glass and it is,
therefore, an ideal hardness measuring instrument for the
scientific research institutes, the universities, the industrial
production units and the metrological institutes using with for
studying and measuring.
