Description of Leeb Hardness Tester LH03

The leeb hardness tester LH03 recently developed is equipped with high energy efficiency. It has a rechargeable battery that lasts long and charges effectively to give high performance. Its USB connectivity ensures an easy interface with other devices and prints instantly on-site with its thermal printer. The display screen is LCD with very high brightness for easy visuals and English as the operating language. 

The other features that make the LH03 awesome include an automatic recognition impact device with up to 7 different types of impact devices. 

It also has a memory to store as many as 450 value groups containing an average value, hardness system, materials, single measurement, and direction. 

Up to 3 intensity values and multiple hardness systems are supported while upper and lower limits are easily set with alerts for when they are exceeded. 

Additionally, the LH03 can interface with applications for different data manipulations like histogram plotting and statistical analysis.

 

Features:

1. Full English display, menu-driven operation.
2. Mini USB communication interface.
3. Can be equipped with 7 kinds of different impact devices, no need to recalibrate when replacing, and can automatically identify the type of impact device.
4. Supports measurement of multiple hardness systems and three intensity values.
5. It can store 450 groups, single measurement value, average value, measurement date, impact direction, times, materials, hardness system and other information.
6. It can set the upper and lower hardness values in advance, and it can automatically alarm when it exceeds the limit, which is convenient for users to need batch testing.
7. Indicating software calibration function.
8. Built-in high-performance lithium battery and charge control circuit, with long working and standby time.
9. Can be equipped with computer software, support for data query, storage, statistics and histogram display and other functions.
