Contact Details
Phase II’s PHT-6000 nondestructive, portable, ultrasonic hardness tester is suitable for small, large, flat, round, thick or thin workpieces. It can test soft metals, such as copper and brass, and hard metals while adhering to ASTM A1038-10 guidelines for portable hardness testing using the static ultrasonic contact impedance method.
The tester can check coating hardness. It can convert and be calibrated to various hardness scales, including HRC, HRB, HRN, HRT, HB and HV.

- Brinell hardness number ( HB)
Brinell hardness number ( HB)
Number related to the applied load (usually, 500 kgf and 3,000 kgf) and to the surface area of the permanent impression made by a 10mm ball indenter. The Brinell hardness number is a calculated value of the applied load (kgf) divided by the surface area of the indentation (mm2). Therefore, the unit of measure of a Brinell hardness number is kgf/mm2, but it is always omitted.
- Vickers hardness number ( HV)
Vickers hardness number ( HV)
Number related to the applied load and surface area of the permanent impression made by a square-based pyramidal diamond indenter having included face angles of 136º. The Vickers hardness number is a ratio of the applied load in kgf, multiplied by 1.8544, and divided by the length of diagonal squared.
- flat ( screw flat)
flat ( screw flat)
Flat surface machined into the shank of a cutting tool for enhanced holding of the tool.

hardness
Hardness is a measure of the resistance of a material to surface indentation or abrasion. There is no absolute scale for hardness. In order to express hardness quantitatively, each type of test has its own scale, which defines hardness. Indentation hardness obtained through static methods is measured by Brinell, Rockwell, Vickers and Knoop tests. Hardness without indentation is measured by a dynamic method, known as the Scleroscope test.
