with LCD Screen and Built-in Printer
 
 
Main Function:
 
HRS-150 Digital Rockwell hardness tester is equipped with a newly-designed large displaying 
 
screen with good reliability, excellent operation and easy watching, thus it is a high-tech product 
 
combining the mechanic and electric features. It can show and set the present scale, test force, 
 
test indenter, dwell time and hardness conversion; the main function is as follows: Selection of all
 
the Rockwell scales; Conversion scales of different kinds of hardness; Test results can be saved 
 
 
and printed out, automatic calculation of maximum, minimum and average value; With RS232 
 
interface for connecting to the computer.
