Digital Brinell, Rockwell, Vickers hardness tester

Multi-function digital display universal hardness tester have high degree of automation, stable and reliable performance, equipped with sophisticated sensors, test is more accurate; A 5.6 inch industry screen provide comprehensive data for quality control, through hardness transmission software export test data into the computer conveniently, easy to long term preservation.


Main function and features:

1. Can meet Rockwell and small load Brinell and Vickers hardness test requirements, its convenient for user to do a variety of materials at the same time.

2. Equipped with sophisticated sensors, test results are more accurate, the leading variable load structure design, can easily switch test force, high test precision, good repeatability.

3. The main components adopt brand such as American 3M, Allegro, Japan Omron and NKK, to ensure the equipment running stably for a long time.

4. Equipped with digital display micrometer eyepiece and data computing systems accurate to 0.01 um, only gently touch, can directly show the Brinell or Vickers hardness value.

5. It is automatic to test when the working platform lifting up to some height, then indicate Rockwell hardness value and various testing data directly. 

6. The industry LCD screen can be visual display hardness value, hardness unit, conversion hardness, testing force, indenter type, the required minimum thickness, load time, measurement times, and the test process is intuitive and clear, built-in printer can print out measured times, hardness value, average, maximum and minimum values, range for the customer to archive.

7. The shell is one step casting molding with special foundry process, stable structure and no deformation, can work under relatively harsh environment; Pure white car painting and its class is high, have scratch resistance ability, its still brightness used for years.

9. We have our own research and development design, production and processing ability, our machines provide life-long time parts replacement and maintenance upgrade services.


Main Uses:

1. Chilled steel, quenched and tempered steel, annealing steel, bearing steel, strip steel, hardened steel sheet, hard alloy, etc.

2. Cast iron, nonferrous metal, especially for soft metal, such as pure aluminum, lead, tin, etc.

3. Carburizing, nitriding and decarburization layer, the surface hardening layer, electric plating and coating.
