Overview and application
This digital leeb hardness tester is with color screen and detachable impact device. It adopts Cortex-M0 core high-performance ARM processor as the main control chip and is equipped with outstanding impact device, which makes the measurement smart, accurate, quick and without damage. It can be used to measure the hardness of common metal materials. Thus, this digital hardness tester is widely applied in the field of mold, heat treatment, machining, pressure vessel, auto parts,aerospace and other industries.
The impact waveform is applied to this digital leeb hardness tester to make you know the working state of impact device. What’s more, A computer software is developed to process the test data, the screen shows all the values in different unit at same time and you can equip this tester with a Bluetooth printer. All of these make the metal hardness tester different.
