DR-3000ZS Double Objective Three-Head Touch Screen Digital Display Automatic Turret Brinell Hardness Tester

The DR-3000ZS dual objective three indenter touch screen digital automatic brick tower Brinell hardness tester features a software system programmed with computer intelligence and employing photoelectric sensing technology. By independently selecting test conditions, all parameters can be directly chosen, modified, and analyzed on a multifunctional PC. The PC is connected to the hardness tester via a communication protocol to control the mechanical movement parts of the tester, enabling functions such as automatic multi-functional tower positioning, automatic recognition of objectives and indenters, automatic rising and lowering, automatic focusing, automatic loading, automatic holding force, automatic unloading, automatic measurement, and light brightness adjustment. By linking to the built-in CCD measurement and acquisition system, clear dynamic images of the indentation can be displayed in real time on the PC, and the hardness value can be automatically measured and locked directly from the indentation. Test data can be automatically saved and reports generated. The optical system uses an LED objective lens. The hardware system adopts electronic sensor loading technology, with a closed-loop control system that controls the sensor to collect signals, and a high-speed stepping motor automatically applies and releases the test force, and can automatically compensate for the test force, providing more stable readings. It is also equipped with an emergency stop device. 

Main functions and features: 

1. Integrated embedded industrial tablet computer, supporting USB expansion.

2. Equipped with the latest Windows operating system.

3. Capable of 11 levels of test force.

4. Data calculation system, hardness value can be directly displayed with just a click.

5. Automatic lifting, no need to manually turn the lead screw.

6. Multi-position turret, equipped with three indenters and two objectives simultaneously.

7. After applying the test force, it can automatically focus on the clearest part.

8. The system has a built-in calibration function, allowing manual adjustment of the input calibration instrument.

9. Convertible scales.

10. Equipped with a stepping motor for automatic loading and unloading of test force, generating less noise during the testing process.

11. Utilizing photoelectric sensing technology and a microcomputer control system, it can automatically compensate, ensuring stable test results.

12. Automatic measurement directly displays the hardness value.

13. LED optical measurement, high image clarity, and less fatigue during long-term operation.

14. Stable shell structure that does not deform, capable of working in relatively harsh environments. 

Functions and features of the automatic measurement control system:

1. Hardness tester control: The system provides serial port communication to control the operation of the hardness tester, such as up and down movement, focusing, objective turret rotation, loading, setting the holding time, and adjusting the light intensity, etc.

2. Test force control: The system automatically controls the test force. The required test force can be switched automatically with just a click.

4. Indentation measurement accuracy: ±0.5%

5. Automatic indentation measurement and calculation of Brinell hardness value.

6. Automatic measurement of the indentation on the test sample and the standard block and calculation of the hammering Brinell hardness value HB2.

7. Automatic measurement: Automatic or manual capture of the indentation and measurement of the indentation diameter and calculation of the corresponding Brinell hardness value.

8. Hardness value conversion and effective verification: The system can convert the measured Brinell hardness value HB into other hardness values such as HV and HR, etc.

9. Data statistics: The system automatically calculates and saves the average value, variance, and other statistical values of the measured hardness.

10. Over-limit alarm: Automatically mark abnormal values. When the hardness exceeds the specified value, an automatic alarm is triggered.

11. Test report: Automatically generate reports in WORD or EXCEL format. Report templates can be customized.

12. Data storage: Measurement data, including indentation images, can be stored in documents.

13. Other functions: Include all the functions of the image processing and measurement system, such as image capture, calibration, image processing, geometric dimension measurement, document annotation, album management, and fixed-magnification printing, etc.

14. Easy to use: Clicking a button on the interface can automatically complete the indentation measurement work. If manual measurement or result modification is needed, simply drag the measurement box.
