Small Portable Rockwell Hardness PHR-4-2

Specifications

Small Portable Rockwell Hardness Tester PHR-4-2

Introduction

 Miniaturization of Rockwell hardness tester, the smallest model
  weighs only 0.8kg and  the operation is similar to that of a
  micrometer.

 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
                                          1.588mm carbide 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.

Application

 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.
