Introduction

  A portable indentation hardness tester.

  Single hand operation; no operating experience required; can
   test any workpiece which is  reachable in any site.

  Wide valid testing range equivalent to Brinell hardness 25-150
   HBW. Used to test the hardness of all kinds of aluminum, 
   from very soft aluminum to very hard aluminum alloys. 

  Extended application. Model 934-1 is applied to test the
   hardness of aluminum, aluminum alloys, copper, copper alloys, 
   fiber reinforced plastics and rigid plastics etc. The improved 
   model of it is available to test very soft metals such as lead 
   and tin and other soft materials such as soft plastics, rubber, 
   felt and leather etc.

  High sensitivity. Featured with 100 scales, much more sensitive
   than Webster hardness testers applied in aluminum alloys
   industry.

  No supporting required. Can test from only one side of the
   workpiece. No need to move or support the workpiece.
   Used to test super large and thick worpieces and assembly
   parts.  

  Easy conversion. The test results can be converted to HB, HR,
   HV and HW easily through conversion table.

  Comply to standard ASTM B648-2000.
