Large portable Rockwell hardness tester is the large size type in PHR series Rockwell hardness testers.

The PHR Series Large Portable Rockwell Hardness Tester can be used on the spot to make a precise test on large-scale molds, forging, axes, tubing and other large metal parts, besides, it can be also used to test the heat-treated work pieces such as annealed, normalizing, tempered, quenched, carburized and induction hardnening.

Tightly compress the work piece first and then apply test force. The test turns out to be of good stability and high accuracy.

The indentations made by this large Rockwell hardness tester are small and its test speed is great, which can be considered as a non-destructive test to test the finished or semi-finished work pieces individually.

The error is less than 1.5HRC verified by the authoritative measurement institution.

Compared with the commonly-used Shore hardness tester,Leeb hardness tester for large-scale work pieces, this instrument has many advantages such as higher precision,fewer factors affecting accuracy and lower requirement on the surface roughness of work pieces; the test result meets the requirements of most drawings without conversion and is more widely accepted in the international business.
