PHR-8/PHR-20 Large portable Rockwell hardness tester (mold hardness tester)Detailed product description：

PHR Large Portable Rockwell Hardness Tester (Mold Hardness Tester)

Overview
*The PHR large portable Rockwell hardness tester is the large-sized part of the PHR series of portable Rockwell hardness testers.
*PHR large portable Rockwell hardness tester is used on site. Can accurately test large molds, forgings, shafts, pipes, and other large metal parts. Test heat-treated workpieces for annealing, normalizing, quenching, tempering, carburizing, and induction hardening.
*First, press the workpiece tightly, then apply a test force to test for good stability and high accuracy.
*Small indentation, fast testing speed, suitable for non-destructive testing, used for piece by piece inspection of finished or semi-finished workpieces
*Compared with the commonly used Leeb hardness tester for hardness testing of large workpieces, it has the advantages of high accuracy, fewer factors affecting testing accuracy, low requirements for surface smoothness of workpieces, no need for conversion to meet the drawing requirements or product standards of most workpieces, and easy recognition in international trade.
*According to testing by the China Institute of Metrology, the error is less than 1.5HRC.
