MHBD-62.5AP Digital Display Small Load Brinell Hardness Tester

Jul 03, 2018

Small load Brinell hardness tester adopts smaller parts of the Brinell hardness value, especially suitable for testing soft materials; this machine is equipped with sophisticated sensors, more accurate test results, using imported components ensure equipment running more stable, the updated control system can provide more measurement data, control is more comprehensive and precision.




Main features

1.       Equipped with sophisticated sensors, both test force and test results are more accurate, have more wide range of test force for your choice.

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

3.       Proprietary ball positioning system have more precision of repositioning, ensure the precision and repeatability of the whole test process .

4.       Designed by our institution engineer that make the optical system imaging more clearer, brightness is adjustable, comfortable vision, it’s not easy to fatigue for long time operation.

5.       Input the indentation diameter, hardness value is displayed directly, and can display conversion hardness value at the same time, avoid the inconvenience of looking up table.

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, it’s still brightness used for years.

8.       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 application

1. It’s suited to test the big size grain metal material, reflecting the combination property.

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