materials. Direct display of hardness scales HRB, HRC, HRA, HV,
HB, HS, HL and three types of strength values immediately.
• Test at any angle, even upside down.
• Seven impact devices are available for special application.
Automatically identify the type of impact devices.
• Large capacity memory can store 100 groups (Relative to average times
32~1) information including single measured value, mean value, testing
data, impact direction, impact times, material and hardness scale etc.
• Battery information shows charge status & remaining battery
capacity during use.
• Auto off function.
• Built in printer.
