Product details
The HLN200 Leeb hardness tester can conveniently and quickly measure various hardness values of multi heavy metal materials (HL, HRC, HRB, HRA, HB, HV, HS).
Adopting a large screen dot matrix LCD (320 × 240) with full Chinese display, user-friendly interface, rich content, beautiful, clear and generous text and graphics, not affected by voltage fluctuations.
To ensure measurement accuracy, it has dual functions of software calibration and hardware calibration, and can be equipped with seven types of impact devices. The host automatically recognizes them and does not need to recalibrate when replacing.
In addition, it comes with preset tolerance limits, over limit alarms, display clocks, and other functions, suitable for on-site batch measurement.

| Product Features |
| ·Equipped with power on self-test function and factory parameter recovery function, ensuring the normal operation of the instrument. It has a 5-minute automatic shutdown function. |
| ·Adopting two operation modes: direct mode and menu mode, the operation is flexible and convenient. All interfaces have operation prompts, which can be used to complete various operations. |
| ·Adopting a large screen dot matrix LCD (320 × 240) with full Chinese display. |
| ·Large capacity storage, capable of storing 500 sets of data, each set of data including: 26 single measurement values, average values, test dates, impact directions, frequency, materials, hardness, and other information. |
| ·The host can be equipped with 7 different impact devices, which automatically determine whether the impact device is connected properly and identify the type of impact device. |
| ·It has dual functions of software calibration and hardware calibration. |
| ·It can be automatically converted into HL, HRC, HRB, HRA, HB, HV, HS, and σ b according to the type, direction, and material of the impact device. |
| ·The upper and lower limits of the hardness value can be pre-set, and the test data can be automatically judged as exceeding the upper and lower limits, and the exceeding data can be automatically deleted. |
| ·The addition of "forged steel" material allows for direct reading of HB values when testing "forged steel" specimens using a D/DC impact device, eliminating the need for manual table lookup. |
| ·It has a warning and alarm function, and special warnings have warning sentences on the display interface. |
| ·Built in intelligent charging protection chip, automatically cuts off the charging power when charging is completed. In the charging state, the instrument can work normally using an external power source without affecting charging. |
| ·Equipped with backlight illumination function, it is convenient for users to use in low light conditions. |
| ·Equipped with RS232 interface, the measured data can be transmitted to the computer for easy management. |
