Automatic Universal Hardness Tester for Production Integral Universal

Automatic image analysis for Brinell hardness tests (1-3000 Kg), Knoop and Vickers hardness tests (0.25 – 120 Kg); this reliable hardness tester ensures a repeatability of +/- 0.002 Brinell. Machine management happens through a built-in computer. This universal hardness tester is perfect for industry as well as for research (as a laboratory hardness tester). It can mount a X-Y table for pieces positioning.

Integral Universal is, as the name suggests, a universal hardness tester able to perform different hardness tests, including Martens test. In fact, it can execute multiple types of measurements, according to DIN-ISO, ASTM DIN regulations, and works perfectly on any type of metal and alloy, as well as on synthetic materials, ceramics, abrasive stones, plastics, rubber, aggregates and many other materials. Upon request, load forces for additional tests can be added.

Integral Universal is characterized by the possibility to execute automatic image analysis for Knoop, Vickers (0.25 – 120 Kg) and Brinell hardness test (1 – 3.000 Kg, with a repeatability of +/- 0.002 Brinell) as well as for all the other hardness tests requiring the reading of the indentation. Readings happen through a built-in camera and are shown on an integrated monitor, providing with high-definition electronic measurement, with precision of 1 micron and a zoom range from 20x to 400x. Moreover, everything is 100% automatic: thanks to the auto focus, aided by the piece presser, and the light intensity adjustment.

WHAT ARE THE MAIN 3 TESTS USED TO TEST HARDNESS?

For steel, and metal in general, we can say that the main hardness tests are, indeed, 3: Brinell hardness test, Rockwell hardness test, and Vickers hardness test (with diamond indenter). Vickers and Brinell, require the possibility to read the indentation with a camera, while Rockwell measures the depth of penetration of the indenter. But hardness is a very wide topic, and a universal hardness tester shall be able to measure not only these three scales.

THE METHODS AND STANDARDS ADOPTED BY INTEGRAL UNIVERSAL ARE

Brinell based on EN-ISO 6506
Vickers based on EN ISO 6507
Rockwell based on EN ISO 6508
Knoop base on EN ISO 4545
Plastics based on DIN 53456
Metallographic controls can be carried out on metal structures and measurements of the depth of the hardness surface treatment can be performed
