Manual Turret Digital Eyepiece Micro Vickers Hardness Tester with Large LCD Mini Thermal Printer
Technical Data Download: iqualitrol Micro Hardness Tester iVick-453H
iVick-453H Digital Micro Vickers hardness tester adopts unique precision design of optics, mechanic and electrics features, make the indentation image clearer, and get more precise measurements.
With iqualitrol digital measuring eyepiece, no need for checking the table or inputting the diagonal of the indentation, it can directly show the test mode, test force, indentation length, dwell time, test numbers, conversion scale, date and time.
As long as press the eyepiece button after measuring the indentation length, it can automatically get the hardness value and show on the large screen.
Test results can be saved for checking or be printed out by the built-in printer, and with RS232 interface for connecting to the computer.
Available to use optional Knoop indenter to measure Knoop hardness.
Support optional LCD video measuring device and CCD image automatic measuring system.
Suitable for ferrous metal, non-ferrous metals, IC thin sections, coatings, ply-metals; glass, ceramics, agate, precious stones, thin plastic sections etc.; hardness testing such as that on the depth and the trapezium of the carbonized layers and quench hardened layers.
Heat treatment, carbide, quench hardened layer, the surface coating layer, steel, non-ferrous metal and small and thin shape parts, etc.

The Vickers hardness test method consists of indenting the test material with a diamond indenter, in the form of a right pyramid with a square base and an angle of 136 degrees between opposite faces subjected to a load of 1 to 100 kgf. The full load is normally applied for 10 to 15 seconds.
The two diagonals of the indentation left in the surface of the material after removal of the load are measured using a microscope and their average calculated. The area of the sloping surface of the indentation is calculated. The Vickers hardness is the quotient obtained by dividing the kgf load by the square mm area of indentation.
When the mean diagonal of the indentation has been determined the Vickers hardness may be calculated from the formula, but is more convenient to use conversion tables.
The Vickers hardness should be reported like 800 HV/10, which means a Vickers hardness of 800, was obtained using a 10kgf force. Several different loading settings give practically identical hardness numbers on uniform material, which is much better than the arbitrary changing of scale with the other hardness testing methods.
The advantages of the Vickers hardness test are that extremely accurate readings can be taken, and just one type of indenter is used for all types of metals and surface treatments. Although thoroughly adaptable and very precise for testing the softest and hardest of materials, under varying loads, the Vickers machine is a floor standing unit that is more expensive than the Brinell or Rockwell machines.
The Knoop hardness test method is mostly used for small parts, thin sections, or case depth work. Knoop indentation is very small, the main application like below:
testing very thin materials like foils or measuring the surface of a part,
small parts or small areas,
measuring individual microstructures,
measuring the depth of case hardening by sectioning a part and making a series of indentations to describe a profile of the change in hardness.
The Knoop indenter is a pyramid shaped diamond is more elongated or rectangular in shape. The Knoop method is commonly used when indentations are closely spaced or very near the edge of the sample.
The width of the Knoop indentation can provide more resolution for measurement and the indentation is also less deep. Consequently, it can be used on very thin materials.
