PHR-2
Portable Rockwell Hardness Tester
PHR-4-2
Portable Rockwell Hardness Tester
Main Features
- It is small, light and easy to operate, and can be used as a micrometer.
- It is flexible in application and can be placed on the table or carried to the site for use.
- The main engine can be used alone or inserted into the supporting seat.
- It can be used to test small, long and special-shaped parts which cannot be tested by bench hardness tester.
- It can test standard parts, hardware, tools, and other parts.
- It can directly test the hardness of the inner and outer wall surfaces of steel pipes.
- It is very suitable for testing parts with a small bearing surface (such as small stamping parts).
- It is equipped with different anvils to test various special-shaped parts.
- It has the same test principle and standard as a desktop computer. It conforms to Rockwell hardness test method.
Application Range
- It is suitable for Rockwell hardness measurement of ferrous metals, alloy steels, non-ferrous metals, non-ferrous alloys, cemented carbides, quenching, tempering and carburizing layers.
