Description
Product Introduction:
The HBS‑3000 digital Brinell hardness tester features a software system based on intelligent computer programming and photoelectric sensing technology. It allows users to independently select test parameters and displays, on an LCD screen, the testing method, upper and lower limit ranges, indenter diameter, hardness values, converted values, test force, dwell time, and number of measurements. Users can also enter the year, month, and date, view test results, and perform data processing. Measurement data can be printed via the built-in printer or transmitted to a computer through a data interface. The optical system employs high‑magnification LED illumination for clear imaging with adjustable brightness, minimizing operator fatigue during extended use. The hardware incorporates advanced electronic sensor‑based loading technology, utilizing a closed-loop control system in which the CPU manages sensor signal acquisition and a stepper motor automatically applies and releases the test force, while providing automatic force compensation to ensure greater accuracy and more stable readings. An emergency stop device is also included, offering user‑friendly operation and enhanced reliability and stability.
Main uses and scope of application:
1. Suitable for hardness testing of metallic materials with coarse grains, it can reflect the material’s overall performance.
2. Cast iron, steel, and nonferrous metals, especially softer metals such as pure aluminum, lead, and tin.
3. It can be used for hardness testing of certain non-metallic materials, such as rigid plastics and bakelite.
Functions and Features:
1. This instrument features high precision, excellent repeatability and stability, simple operation, practical convenience, and a favorable price‑performance ratio.
2. Equipped with a 10-level test force, it can accommodate a wider testing range;
3. Equipped with a digital display micrometer eyepiece and a data calculation system, it can directly display the hardness value with a single click.
4. Equipped with a built-in printer for outputting measurement data, or networked to a computer to transmit the host’s measurement data for editing and storage.
5. Equipped with a high-performance stepper motor for automatic application and removal of test force, resulting in reduced noise during testing.
6. Utilizing photoelectric sensing technology and a microcomputer control system, automatic compensation is achieved, ensuring accurate and stable test results.
7. Automatically inputs the indentation diameter and directly displays the hardness value; it supports dual display of any hardness scale, eliminating the need for tedious table lookups.
8. Self‑contained design with high‑magnification LED optical measurement, offering high image clarity and adjustable brightness to reduce operator fatigue during extended use.
10. The housing is cast in a single piece, ensuring structural stability and resistance to deformation, enabling operation in relatively harsh environments.
11. The surface is finished with automotive baking‑paint technology, offering excellent resistance to scratches and maintaining a bright, like‑new appearance even after years of use.
