LH 180 leeb hardness tester
Identify the type of the percussion device automatically
can be fitted with computer software, supporting data query, storage, statistics and histogram display, and other functions
Preset upper and lower limit of hardness value, automatic alarm if beyond this range.
Meet the batch testing needs
Can store 373-2688 group (shock times 32 ~ 1)of information of single measured value, average value, measuring date, number, material, hardness, percussion direction and other information
Supports measuring many kinds of hardness value and 3strength value Calibration function
Applicable to metal materials
Mini USB communication interface
Can be equipped with seven different impact devices,does not need to recalibrate when the device is replaced with each other, identify the type of device automatically.
Alarm to indicate the insufficiency of voltage.
