MH310 portable Leeb hardness tester, based on Leeb hardness measuring principle, quick and easy on-site 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 clear ,stable performance. integrated high-speed thermal printer ,which can print on-site measurements. It is widely used in annealing, tempering, quenching , quality control for the work piece; hardness testing for machine tool and automobile chassis ; on-site hardness testing of in-service non-removable parts ; quality testing for hardware, forging, machine tools and special steels; quality control for batch production process and so on.Good quality and effective cost ,which is a wise choice for regular need of hardness testing .
The energy quotient is quoted in the hardness unit HL and is calculated from comparing the impact and rebound velocities of the impact body. It rebounds faster from harder samples than from softer ones, resulting in a greater energy quotient which is defined as 1000×Vr/ Vi.
HL=1000×Vr/ Vi
Where:
HL— Leeb hardness value
Vr — Rebound velocity of the impact body
Vi — Impact velocity of the impact body

After the impact device has been used for 1000 to 2000 times, please use the nylon brush provided to clean the guide tube and the impact body. Follow these steps when cleaning the guide tube,
1.unscrew the support ring
2.take out the impact body
3.spiral the nylon brush in counterclockwise direction into the bottom of guide tube and take it out for 5 times
4.install the impact body and support ring when complete.
Release the impact body after use.
Any lubricant is prohibited inside the impact device.
