Portable Rockwell Hardness Testers PHR-1/2/4

[Specifications]:
Small Tester;
Miniaturization of Rockwell hardness tester;
Weighs only 0.8kg;
[Portable Rockwell Hardness Testers PHR-1/2/4 Product details]:
The testing principle and accuracy comply with ISO 6508 and ASTM E110, tested by National Institute of Metrology with error less than 1.5HRC, same as the bench type.
The instrument is composed of tester and bench stand, can be used on table or on site in the factory.
Can test many kinds of thin, small, long and irregular parts that cannot be tested by the bench type.
Well suits for testing the workpieces with small supporting surface.Traceable standard hardness block.
Indenter inspected with standard Rockwell hardness tester.
Test force calibrated with load cells directly traceable to national secondary benchmark. 
 

Main Technical Parameters
Initial Test Force:                 10kg                           
Total Test Force:                  60kg, 100kg, 150kg
Force Applying Method:        By screw
Indenter:                               120°diamond cone
                                             Ф1.588mm car ide ball
Accuracy:                             Meets the requirements of ISO6508
Resolution:                          0.5HR
Testing Range:                    HRA, HRB, HRC… HRV, etc. 15 scales.
Application:                         All metals, including steel, cast iron,copper, aluminum, nickel, titanium,
                                           Lead, tin, carburized steel, carbide alloy, etc.
Small hardness tester is portable at reasonable price, well suits for small parts testing. The reliability & repeatability of small hardness testers with 4 inches opening size will be reduced when testing large workpieces, large Rockwell hardness tester is the priority choice in such situation.
