KH320 Portable Hardness Tester

Advantages

• Large screen(128×64 dot matrix LCD), showing all functions and parameters.

• Test at any angle, even upside down.

• Wide measuring range. It can measure the hardness of all metallic materials. Direct display of hardness scales HRB, HRC, HV, HB, HS, HL and three types of strength values immediately.

• Seven impact devices are available for special application. Automatically identify the type of impact devices.

• Large capacity memory could store 500 groups (Relative to average times32～1 ) information including single measured value, mean value, testing data, impact direction, impact times, material and hardness scale etc.

• Upper and lower limit can be preset. It will alarm automatically when the result value exceeding the limit.

• Battery information indicates the rest capacity of the battery and the charge status.

• User calibration function.

• USB port with the PC humanity multi-functions data proceeding software.
