Ultrasonic Hardness Meter

The ultrasonic hardness tester reflects the hardness of materials by measuring the change in vibration frequency of ultrasonic waves at the contact surface between the indenter and the material, based on the principle of acoustic impedance matching. Its function is to perform non-destructive hardness testing on materials such as metals and ceramics, and it is applied for on-site rapid testing of mechanical parts, heat-treated workpieces, and thin-layer materials.
Selection
When selecting an ultrasonic hardness tester, consider the type and hardness range of the material to be tested, ensuring the instrument supports the corresponding scale; choose between portable or benchtop models based on the testing environment; verify the compatibility of the indenter type with the test surface; confirm the instrument's calibration certificate and measurement repeatability; and ensure the probe compatibility and data output functions meet recording requirements.
