1、 Overview:
The HLN200 portable Leeb hardness tester, based on the Leeb hardness measurement principle, can conveniently and quickly measure various metal materials. While displaying the hardness measurement value immediately, it can freely switch between different hardness standards, pre-set tolerance limits, and automatically alarm when exceeding the range. The product adopts the internationally popular fully enclosed metal shell, which is sturdy and durable, and has excellent anti electromagnetic, anti vibration, and anti interference capabilities. Relying on stable low-power IC integrated circuits, fully Chinese display, simple and convenient menu operation, seven types of irregular impact devices do not require calibration, automatic recognition. USB interface transmission, large capacity storage, and comes with PC humanized data processing software and USB plug and play data cable. 50 hours of standby time, powered by AA No. 5 ordinary battery, easy to carry, and more flexible to replace. Especially suitable for work sites and field operations

5、 Product Features:
Fully sealed metal casing, compact, portable, highly reliable, suitable for harsh operating environments, strong resistance to vibration, impact, and electromagnetic interference, sturdy and durable;
According to the principle of Leeb hardness measurement, various metal materials can be tested. The measurement range is wide, and there are no shape restrictions on the measured workpiece. It supports 360 degree measurement direction and has a software calibration function for startup indication, which can ensure that the data is applicable and accurate under different specifications and standards in any industry.
Supports multiple hardness tester systems including Rockwell (HL), Brinell (HB), Rockwell B (HRB), Rockwell C (HRC), Rockwell A (HRA), Vickers (HV), and Shore (HS). Parallel conversion between hardness and hardness can be performed before and after measurement.
Excellent compatibility performance, seven types of impact devices do not require calibration and automatic recognition. The price of the special-shaped impact device and series of special-shaped support rings is reasonable, meeting the maximum needs of different customers and fields.
Full Chinese large screen 128 * 84 graphic dot matrix LCD display with EL backlight support, convenient for use in low light environments.
The host panel features a fully Chinese menu style operation, and the circuit design embodies a humanized concept. With just one click, materials and hardness can be switched freely, making it simple and convenient.
Equipped with a USB plug and play interface, the standard configuration comes with PC data processing software for easy and fast data exchange and parameter setting with the PC.
Large capacity storage of up to 500 sets of hardness measurement data (impact frequency 32-1), each set of data including single measurement value, average value, measurement date, impact direction, frequency, material, hardness system, and other information. Using software to connect to a computer can also achieve massive storage
The upper and lower limits of the hardness value can be pre-set, and an automatic alarm will be triggered if it exceeds the range, which is convenient for users to test in batches.
Supporting "Steel" materials, when testing "Steel" specimens with D/DC type impact devices, the HB value can be directly read without the need for manual table lookup.
It has energy-saving functions such as automatic sleep and automatic shutdown, low-power design, powered by 2 AA No. 5 batteries for easy replacement, and stronger battery reliability.
