Portable Rockwell Hardness Tester PHR-1 Series

 

---

 

Applications:

The PHR series is a high-precision portable hardness testing instrument designed to evaluate both metallic and plastic materials. It is suitable not only for small components but also for large parts, effectively overcoming the limitations of bench-top hardness testers that cannot be moved to test large or fixed workpieces. Additionally, it addresses the limitations of rebound-type testers, which are not accurate when measuring small parts.

 

Portable Rockwell superficial hardness testers (HR) are a variation of standard Rockwell hardness testers. They use lower test forces, resulting in smaller indentations, making them ideal for testing thin and small workpieces such as thin metal sheets, tubes, slender shafts, small balls, hardened materials, and other metal parts that require minimal surface indentation.

.

The testing range covers:

 

• Low hardness materials such as aluminum, lead, and tin
• Medium hardness materials such as aluminum alloys, copper, copper alloys, stainless steel, cold-rolled sheets, and tinplate
• High hardness materials such as thin hardened steel strips, carburized steel, and nitrided steel

 

Test results are read across 15 scales, including N, T, W, X, and Y. Accuracy complies with GB/T 230, ISO 6508, and ASTM E18 standards.

 

Testing is accurate, relatively fast, and simple to perform. The small indentations are generally non-destructive for most samples, making the instrument ideal for on-site, piece-by-piece inspection of finished or semi-finished workpieces.

 

Additionally, test results can be converted into HV (Vickers), HB (Brinell), or tensile strength values using standard conversion tables.
