I.Features: Wide measuring range.Based on the principle of Leeb hardness testing theory.It can measure the Leeb hardess 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,Support rings for shaped materials. 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,suitable for use under poor working conditions. Continuous working period of no less than 100 hours with two alkaline batteries(AA size),Auto power off to save energy.
