1.      Overview 
1.1    HMR Advantages 
 

 

Wide measuring range based on the principle of 
Leeb Hardness testing theory. Leeb Hardness of 
all metallic materials can be measured. 

 

Large screen (128 x 64 dot matrix LCD) showing 
all functions and parameters. 

 

Testing at any angle, even upside down 

 

With EL background light 

 

Direct  display  of  hardness  scales  HRB,  HRC, 
HV, HB, HS, HL 

 

Seven  impact  devices  are  available  for  special 
applications. Automatical identification of type of 
impact devices 

 

Large  capacity  memory  can  store  500  groups, 
information  including  single  measured  value, 
mean  value,  testing  date,  impact  direction, 
impact times, material, hardness scale etc. 

 

Upper and lower limit can be preset. It will alarm 
automatically if the result value is exceeding the 
limit. 

 

Battery  information:  rest  capacity  of  battery  is 
indicated.
