HL mini01 integrated Leeb hardness tester

1、 Product Overview
The integrated hardness tester is a portable hardness tester that is easy to use and can be used for hardness measurement of most metals. This instrument combines modern electronics and shock devices, providing a good cost performance ratio. This standalone tester does not require any other display devices, cables, or computer hardware. Ideal for quality control, incoming inspection, and comprehensive product testing with a lightweight and compact design. The portable hardness tester's user-friendly interface and practical functions make it an ergonomic integrated rebound hardness tester.

2、 Functional Features
According to the standardized testing of DIN 50156 and ASTM A956.
Automatic recognition and compensation of impact direction - high accuracy
Large size, easy to read, high contrast LCD display - easier to read
Convert individual readings and averages to universal hardness units (Vickers, Brinell, Rockwell C, Rockwell B, Shore)
Easy to operate - set all test parameters through a 3-key keyboard.
Self diagnosis
Aluminum shell for aviation - sturdy and durable
The intelligent start/standby power switch achieves optimal battery charging life.
The internal lithium battery can be charged through a USB interface or an optional external charger.
According to the principle of Leeb hardness measurement, high-precision testing can be performed on various metal materials.
L supports "Steel" materials, and when testing "Steel" specimens with D/DC impact devices, the HB value can be directly read without the need for manual table lookup.
L * Color LCD display, rich in information, easy to use without obstruction in strong light. Very suitable for field work.
L * Chinese and English menu operating system, easy to switch, concise and convenient.
Built in national standard GB, American standard ASTM, European standard, and international standard ISO, depending on the model.
L * It has Bluetooth output printing function [depending on the model].
Lithium ion battery, capable of continuous operation for no less than 80 hours.
L * has a dual display function for hardness values, which can be switched freely.
L * Aviation aluminum shell, compact, portable, highly reliable, suitable for harsh operating environments, resistant to vibration, impact, and electromagnetic interference.
The USB communication interface facilitates data exchange and parameter setting with a PC, depending on the model.
L can store up to 1000 sets of hardness measurement data (impact times 32-1). Each set of data includes information such as single measurement value, average value, measurement date, impact direction, frequency, material, hardness system, etc.
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.
L has a 2-minute automatic shutdown function without operation.
Low voltage alarm function, prompting users and charging.
L has indication calibration function.
L can be equipped with powerful microcomputer software, which has rich functions such as transmitting measurement results, storing and managing measurement values, statistical analysis of measurement values, printing measurement reports, etc., to meet the higher requirements of quality assurance activities and management.
Design basis standard: "Technical Conditions for Leeb Hardness Tester" JB/T 9378-2001.
