Portable Leeb Hardness Tester can easily and quickly determin the hardness of metal

The testing principle of the Leeb hardness tester is that under certain speed and the specified impact body force the testing surface, calculate  the hardness value from the rate of rebound velocity and rush velocity at 1mm distance of  testing surface.

The Portable Leeb Hardness Tester is color display, windows interface, easy to operate and powerful.

The measured hardness value can be freely converted to rockwell, brinell and other hardness scales.

1. with upper and lower limit alarm by preset

2. Metal shell, strong and durable

3. Support free switching of 6 languages

4. Low power consumption and large storage capacity.Stable and reliable performance.

5. It can automatically identify the type of probe

6. Wide application.Used for testing in the field of pressure vessel, platforms for vehicles, die cavity of molds, heavy work piece, and the installed machinery and permanently parts. quality control in mass production process.

7. Capable to out put data.

Support Ring

surface workpiece is often encountered, encountered, and various surfaces have different influences on the hardness test results. 

 the instant impact falls on the surface of the specimen is the same as that of the plane specimen, so the universal support ring for this Hardness Measuring Instrument,Steel Hardness Tester are required

Under the condition of correct operation, the instant impact falls on the surface of the specimen is the same as that of the plane specimen, so the universal support ring is enough.

However, when the curvature is small enough to a certain size, due to the significant difference in elastic state of deformation under plane conditions, the rebound velocity of the impact body will be low, so that the Leezer hardness value is low.Therefore, it is recommended to use small support rings when measuring samples.

For the sample with smaller radius of curvature, it is recommended to choose the hetero-shaped support ring.
