XHB-3000Z Three head Digital Brinell Hardness Tester

XHB-3000Z Three head Digital Brinell Hardness Tester

One Product Description:

1. Brinell hardness is one of the important indicators of material mechanical properties, and hardness testing is used to determine the quality of metal materials or parts

Important means. Due to the correlation between the hardness of metals and other mechanical properties, most metal materials can

By measuring the hardness value, other mechanical properties such as strength, fatigue, creep, and wear can be approximately calculated. Brinell hardness

Testing can basically meet the hardness requirements of all metal materials by using different test forces and ball indenters

determination.

2.This instrument adopts a precise structural design and is equipped with 3 pressure heads and 2 sets of objective lenses. The test force is applied directly by the force sensor

Connect the control to make the overall structure compact, and ensure smooth and accurate loading and unloading test force. The testing process is controlled by the CPU in the electrical field

Automatic switching is used between the mirror and the pressure head, and mechanical and electronic dual cooperation is used to switch positioning, resulting in higher positioning accuracy. choice

After the corresponding ruler starts, the hardness tester will automatically select the indenter and objective lens to achieve measurement automation.

3.This instrument is suitable for measuring cast iron, non-ferrous metals, and alloy materials, as well as various annealed and quenched and tempered steels, especially

The hardness values obtained from testing softer metals such as aluminum, lead, tin, etc. are more accurate.

II Its main functions are as follows:

1. This instrument has 10 levels of testing force and 13 types of Brinell hardness testing scales, which can be freely selected;

2. Equipped with two sets of objective lenses, 1 ╳ and 2 ╳, both of which can participate in the measurement of indentation diameter;

3. Equipped with three sets of ball pressure heads, all of which can automatically participate in testing;

4. Automatic switching between objective lens and indenter;

5. Pre set the test force holding time and adjust the strength of the indentation light source for measurement;

6. Display the measured indentation length, hardness value, measurement frequency, etc;

7. Conversion values between various hardness scales can be selected;

8. The hardness test results can be printed out;

9. The hardness tester can also be equipped with CCD photography devices and Brinell hardness image analysis software according to users' special needs.
