HL-300 Intelligent Leeb Hardness TesterDetailed product description：

The HL-300 intelligent Leeb hardness tester has the characteristics of high testing accuracy, small size, comprehensive functions, simple operation, easy portability, and wide measurement range. It can automatically convert the Leeb hardness value it can measure into hardness values such as Brinell, Rockwell, Vickers, and Shore, as well as the strength value of the tested material, and can store and print them. It can be equipped with domestic and imported impact devices such as D, C, DC, DL, D+15, G, E, etc., to meet the needs of different testing occasions
