BERINELL HARDNESS TESTER ( ELECTRONIC MICRO-PROCESSOR BASED)

Automatic – Electronic Brinell Hardness Tester

EHB-3000A/3000E:

The EHB-3000A/3000E
Brinell Hardness Tester Testing creates the largest indentation comparing all other hardness testing methods. It is able to reflect the comprehensive features of the material, and is unaffected by the microstructure and inhomogeneous of the specimen. So it with high precision and widely used in industry such as metallurgy, forging, casting, unhardened steel and nonferrous  metals, as well as in the laboratories, universities  and scientific research institutes.

EHB-3000A/3000E Tester Conforms to :
•    ISO6506 Metallic Materials – Brinell Hardness Test
•    ASTM E-10 Test Method for Brinell Hardness of Metallic Materials. 

Specifications:
-    Innovate closed- up technology. The tester incorporates the latest load cell technology. The test load is applied via a closed loop control 
     unit with a load cell, a DC motor and an electronic measurement and control unit. The result is highly accurate measurements at all test loads up to 0.5%. the common load overshoot or undershoot as known from traditional dead weight, or open – loop , system is eliminated. The absence of mechanical  weight  not only eliminates friction problems but also make the equipment less sensitive tocmisalignments caused by vibrations.
-    The whole weight of the  tester is 50% less than the traditional dead weights type tester
-    Test load selection by keyboard and LCD screen. No need of handling heavy weights or clearing the mess oil.
-    Fully automatic test cycles. The hardness tester features a fully automatic test cycle, load application , holding, unloading, is performed 
      fully automatically. This greatly improves reproducibility of test results since operator influence is eliminated.
-    Selectable dwell times by screen. The indenter , load, and other test information are showing clearly on the LCD screen
-    The directions for 0.102F/D2 ratios selecting according to the materials and hardness range can be showing on the screen.
-    Equipped with the special Brinell indention measure system which a new measuring method by using CCD camera to capture the 
      indention image, instead of reading  diameter from optical microscope by operator then calculating the test value.
-    The EHB 3000A tester can connect any PC with USB port and running the SPC software, then the special software supplying simplest 
      operation as following:
-    Both single testing batch testing mode are available
-    Tolerance setting, distinguishing and alarming
-    Statistic values such as Max. Min. Avg. T and S are available 
-    Convert test result to other scales, such as HRC, HRB, HRA, HV, ob
-    All test results and indention images are saved automatically
-    Test report crated in Microsoft EXCEL format, can be edit, copy print as you will
-    Software update freely
