ZHB-3000A Fully automatic Brinell Hardness Tester

Hardness is one of the important indices of material mechanical performance. And hardness test is the important means to determine metal material or the quality of product parts. Because of the corresponding relation between metal hardness and other mechanical performance, therefore, most metal materials can be measured the hardness to approximately calculate the other mechanical performance, such as strength, fatigue, creep and wear. Brinell hardness test can satisfy the determination of all the metal material hardness by using different test forces or changing different ball indenters.

The instrument adopts integrated design of hardness tester and panel computer. With the Win7 operating system, it has all the functions of the computer.

With CCD image acquisition system, it directly shows the indentation image and automatically gets the Brinell hardness value. It takes over the old method of measuring the diagonal length by eyepiece, avoids the stimulation and visual fatigue of the light source of the eyepiece, and protects the eyesight of the operator. It is a major innovation of Brinell hardness tester.

The instrument can apply to the measurement of cast iron, nonferrous metal and alloy material, various annealing, hardening and tempering steel, especially the soft metal such as aluminum, lead, tin etc. which makes the hardness value more correct.
