20X Microscope Hardness Testing Machine Closed Loop Sensor 10 Steps Force

Closed Loop Sensor 10 Steps Force Electronic Brinell Hardness Tester with LCD

Model: HBE-3000A

HB-3000A Electronic Cast Iron Brinell Hardness Tester apply closed loop sensor loading, the electronic control system, has 10 steps testing force, it has high precision, high repeatability and stability, simple operation, etc

Features:

1, High accuracy compression sensor to feedback and the CPU control system to automatically compensate the test force lost during the testing.

2, 10 Steps Testing force for wider application;

3, Equips with stepping motor to realize automatic loading, dwell and unloading, with much lower noise during testing;

4, Die casting metal shell, stable structure, able to work under rugged environment;

5, Surface with car baking process, strong resistance of scratches, still brightness after years using;

6, Available to install optional Brinell measuring software, largely improve working efficiency.

Applications:

Suitable for cast iron, steel products, nonferrous metals and soft alloys etc. Also suitable for some nonmetal materials such as rigid plastics and bakelite etc.

Because of the wide test force range the Brinell test can be used on almost any metallic material. The part size is only limited by the testing instrument's capacity.

Strengths:

One scale covers the entire hardness range, although comparable results can only be obtained if the ball size and test force relationship is the same.

A wide range of test forces and b all sizes to suit every application

Nondestructive, sample can normally be reused

Weaknesses:

The main drawback of the Brinell test is the need to optically measure the indentation size. This requires that the test point be finished well enough to make an accurate measurement.

Each measurement takes 30 seconds not counting the sample preparation time.
