1.  Product  Overview

This  tester  is  easy  to  use  and  supports  high  accuracy.  Its 
operating  principle  is  to  measure  by  using  the  depth  difference 
of  the  test  traces  caused  by  the  initial  load  and  the  test  load. 
At  this  time,  10  kgf  is  applied  to  the  initial  load,  and  the  test 
load  is  determined  by  increasing  the  load.  This  Rockwell 
hardness  tester  can  measure  even  nonmetal  materials  like 
plastics  as  well  as  soft/hard  metal  materials.   

2.  Features

2.1  The  tester  uses  the  automatic  motor  operation  method  that     

        has  no  personal  error  while  measuring. 

2.2  The  indicating  lamp  turns  on  during  the  test.  It  is  easy  to       

  construct  a  test  environment.

2.3  The  load  hold  time  can  be  controlled  directly.

2.4  Relatively  soft/hard  materials  can  be  measured  exactly.

2.5  The  hardness  value  is  displayed  in  the  digital  display  part  to   

        enable  reading  the  value  directly.

2.6  Test  trace  remains  fine,  and  it  does  not  influence  the  product  test.

2.6  Measurement  range  is  wide.
