portable Leeb hardness tester can quick and easily test the hardness of series metal materials, support free conversion between Leeb, Brinell, Rockwell hardness scale and others,It uses high-contrast segment LCD to display , small size,light,portable, stable and reliable performance.It is widely used in failure analysis of metal processing and manufacturing, special equipment, permanent assembly, inspection and other fields.It can meet the regular hardness testing of industrial production , quality and cheap, which is the first choice forpractical and economical models.
The basic principle is to use an impact body of certain weight impacts against the testing surface under certain test force, then measure the impacting velocity and the rebounding velocity of the impact body respectively when the spherically test tip is located 1mm above the testing surface.
The calculation formula is as follows:
HL=1000×VB/ VA
Where:
HL—— Leeb hardness value
VB—— Rebounding velocity of the impact body
VA—— Impacting velocity of the impact body
