Digital Micro Vickers Hardness Tester TH710/711

TH710 /711 Micro Vickers hardness tester adopts unique precision design of optics, mechanic and electrics features, make the indentation image clearer, and get more precise measurements. It can directly show the test mode, test force, dwell time, test numbers, conversion scale on the screen, only need to input the diagonal of the indentation when operation, it can automatically get the hardness value and show on the screen. It can use optional Knoop indenter to measure Knoop hardness. And it can be equipped with CCD image automatic measuring system.

Features

Unique and precise design in mechanics, optics and light source for clearer indentation and hence a more precise measurement.

20 × lens and a 40 × lens the tester enable a wider measurement field and a broader usage range.

Equipped with a digital microscope, it shows the measuring method, test force, diagonal length of indentation, hardness value, dwell time and the times of measurement.

TH711: equipped with auto turret to prevent maloperation.

Automatic loading and unloading technique

Conform to GB/T4340, ISO6507, JIS B7725 and ASTME92 standards.

Application Range

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.
