1 Overview
1.1 Advantages
Wide measuring range. Based on the principle of Leeb hardness testing theory. It can measure the
Leeb hardness of all metallic materials.
Large screen LCD, showing all functions and parameters. With EL background light.
Seven impact devices are available for special application. Automatically identify the type of impact
devices.
Test at any angle, even upside down.
Direct display of hardness scales HRB, HRC, HV, HB, HS, HL
Large memory could store 100 groups (Relative to average times 32
～
1 ) information including
single measured value, mean value, impact direction, impact times, material and hardness scale
etc.
Battery information showing the rest capacity of the battery.
User calibration function.
Software to connect to PC via RS232 port. Micro printer support.
Compact plastic case
