PHASE II brand Leeb Hardness Tester PHT-3300 is a new type of mini integrated Hardness Tester, which has the characteristics of high test accuracy, small size, easy operation, convenient portability, and wide measurement range. It is mainly used to test the hardness of metal materials, and is widely used in many fields of industry.

Leeb Hardness Tester PHT-3300 is designed according to the principle of Leeb hardness test, the measured Leeb hardness value is automatically converted into Brinell, Rockwell, Vickers, Shore and other hardness values through the built-in program, and can also be configured with various test accessories to meet various test conditions and environments. It is mainly suitable for rapid hardness testing of metal materials, especially suitable for on-site hardness testing of large parts and non-detachable parts.
