COMPANY PRODUCT

Features:
● This Rockwell hardness tester is small, portable, accurate, light weight only 0.8kg, and can be easily operated like micrometer.
● Our Rockwell portable hardness tester works on practical hardness testing principle, having the same high testing precision as that of a bench type device. It has high testing accuracy complies with the ISO6508 standard, with an error of no more than 1.5HRC, tested by the National Institute of Metrology.  
● The Rockwell portable hardness tester can be adopted for testing fine, long, small and irregular parts, instead of the bench hardness tester.
● Comprising the main unit and holder, the hardness tester can either be used on the table or easily carried to workshops.
● It is fast, only 10 seconds to finish a test.
● Rockwell hardness value can be conveniently read out.
● The internal and external surface hardness of steel tubes can be tested by the Rockwell portable hardness tester.
● This testing device suits parts with small bearing surface, in particular.
● It is designed with traceable standard hardness block, and penetrator passing the inspection by standard Rockwell hardness tester.
● The load cell used to calibrate load can be traced to national secondary standard.

Applications:
PHR series is a precisely portable hardness testing instrument for the measurement of metal and plastic material, it is not only suitable to measure the small parts, but of metal and plastic material, it is not only suitable to measure the small parts, but tester can not move to test the large and fixed parts, but also offset the problem that the rebound  hardness tester can not make a accurate testing for small parts.
