  Introduction   

 The HL－11 Hardness Tester is designed according to  

the Leeb Hardness principle. It is the result of our 

many years of accumulated knowledge and experience  

designing hardness tester.

All you need for quick, exact，convenient hardness measurement !                                                                                                                               

Specification                                                                                                                              

   Accuracy : ±0.8%(HLD=800)                                                  

      Measuring range: HL300-900, HB80-650, HRB17.5-101

Metallic material: steel and cast steel, alloy tool steel,                                                                      

 stainless steel, grey cast iron, nodular                                                                                        

cast iron, cast aluminum alloy, brass,  

　    bronze, copper, bearing steel.  

       Direction:  measures in any direction  

Impact Devices 

Device D: Universal standard unit. For the majority of hardness testing.

          Device DC: Short impact device for measuring under very restricted  

               space conditions; Otherwise same as device D.

                              Application: → in very confined spaces.      

               → inside bores, cylinder.  

          Device D+15: The front part of this impact device is extremely slender   

                               shaped and the coil recessed for 15mm.   

                                Application: → in grooves and on recessed surfaces.  

           Device DL: Extremely slim front section  

                Aplication: → in extremely confined spaces.  

              →at the base of grooves.

  Device C: Reduced impact energy(approx 1/4 of that for D)

                           Application: → on surface hardened components, coatings   →min. layer thickness of 0.2mm.

                         →on thin walled or impact sensitive workpieces(small measuring indentation).

Device G: Increased impact energy (approx.9 times that of D)  Application: →for measurements in the Brinell-range.

                                  →e.g. on heavy casting and forgings.    →lower demands on measuring surface finish.

            Device E: Synthetic diamond test tip (approx. 5000HV)  Application: →for measurements in the extremly high range

                 →e.g. cold work tool steel with carbide inclusions. →on rolls in the hardness range up to 1200HV.
