DR-62.5 Digital Display Small Load Brinell Hardness Tester

The DR-HBS-62.5 digital small-load Brinell hardness tester is a high-tech product integrating optics, mechanics and electronics. This machine features a novel design and offers excellent reliability, operability and intuitiveness. It is a new type of Brinell testing instrument that combines mechanical and photoelectric technologies. The machine is programmed with computer software and equipped with an optical measurement system. Through soft key input, different indenter types and force values can be selected for measurement. The intensity of the measurement light source can be adjusted in 20 levels, and the holding time can be set. The LCD display shows the indenter diameter, test force, measurement range, and the hardness value can be directly read from the screen, eliminating the need for cumbersome table lookup. It is easy to use, and the measurement accuracy is higher due to the use of a rotary encoder. As the Brinell hardness test applies high pressure and has a large indenter ball diameter and large indentation diameter, it is suitable for hardness measurement of metals with large grains, such as cast iron, non-ferrous metals and their alloys, various annealed and quenched and tempered steels, and most steels supplied from factories. This instrument uses a relatively small part of the Brinell hardness force value, making it particularly suitable for softer metals such as pure aluminum, copper, lead, tin, zinc and their alloys, and the measured hardness is accurate. Brinell hardness has high measurement accuracy, thus providing good reproducibility and representativeness.

Main functions and features:

1. 4-inch large-screen LCD display with menu structure.

2. Automated testing process, easy to operate.

3. High-definition optical system with 20-level adjustable light source brightness.

4. Hardness value conversion function and upper and lower tolerance judgment for hardness.

5. Diagonal lengths D1 and D2 are input by encoder to reduce human reading errors.

6. Test results and data processing can be output through a printer.

7. The shell is cast in one piece, with a stable structure that does not deform, and can work in relatively harsh environments.

8. The surface is treated with automotive paint, with strong scratch resistance, and remains bright and new after years of use.

Main applications and usage scope:

1. Suitable for hardness testing of metals with large grains, which can reflect the comprehensive performance of the material.

2. Cast iron, steel, non-ferrous metals, especially for softer metals such as pure aluminum, lead, tin, etc.
