YD-3000A Leeb Hardness Tester Metal Hardness Meter Measuring Range 170-960 HLD

Features:

1. Based on the Leeb hardness measurement principle, it can perform high-precision testing on a variety of metal materials.

2. Supports "Forged Steel" materials. When testing "Forged Steel" samples with a D/DC type impact device, the HB value can be read directly without the need for manual table lookup.

3. Conveniently switch to other hardness standards (HL, HB, HRB, HRC, HRA, HV, HS) and convert the test values of each hardness standard in parallel.

4. It adopts a large-screen 128×64 graphic dot matrix LCD display, which provides rich and intuitive information.

5. Full Chinese display, menu-driven operation, simple and convenient to use.

6. Fully automatic backlight display, convenient for use in dimly lit environments.

7. RS232 communication interface, which can facilitate convenient and quick data exchange and parameter setting with PC.

8. One main unit can be equipped with 7 different impact devices and automatically identifies the type of impact device. No recalibration is required when replacing them.

9. It can store 600 sets of hardness measurement data (impact count 32 to 1). Each set of data includes information such as single measurement value, average value, measurement date, impact direction, number of impacts, material, and hardness system.

10. The upper and lower limits of the hardness value can be preset, and an alarm will be automatically triggered if the value is exceeded, which is convenient for users to conduct batch testing.

11. Power supply uses two AA (size 5) ordinary alkaline batteries, which can work continuously for no less than 150 hours, and has power-saving functions such as automatic sleep and automatic shutdown.

12. The LCD screen displays a remaining battery level indicator icon to remind users to replace the battery in a timely manner.

13. It has a value indication software calibration function.

14. It can be equipped with feature-rich microcomputer software, which has a wealth of functions such as transmitting measurement results, storing and managing measurement values, statistically analyzing measurement values, and printing measurement reports, to meet the higher requirements of quality assurance activities and management.
