Model Number

PHR-8-4, PHR-8-12, PHR-20-12

On-site hardness test for large workpieces such as large or extra large moulds, castings, forgings, shafts, rollers, pipes and assembled parts as well as other large machinery parts such as annealed, quenched, high efficiency quenched, quencheded and tempered and cemented metal parts.

Small indentation, high efficiency, available for NDT and one-by-one test for finished batch products or semi-finished workpieces.

Accuracy is higher more than 1 time than that of normal-used Leeb hardness testers, less factors that affect test accuracy, lower requirement on the roughness of test part? surface, more acceptable in international trade business. Readings meet the requirements of most workpieses?standards and no need to be converted.

Readings can be converted into HB or tensile strength values(σb) .

Tianxing Rockwell testers read directly in fifteen Rockwell scales:A, B, C, D, E, F, G, H, K, L, M, P, R, S, and V.

Test method and accuracy comply with GB/T230, ISO6508 and ASTM E18.

Accuracy ≤+/-1.5HRC.
