MODEL HRS-150 ROCKWELL DIGITAL 
DISPLAY HARDNESS TESTER
กก MODEL HR-150A 
ROCKWELL HARDNESS TESTER

This tester, which won the national quality silver medal prize in 1989, is one type of practical semi-automatic hardness measuring instrument. It can be widely applied in the factories, scientific research institutes and laboratories of colleges, for deter- mining the Rockwell hardness of ferr ous, non-ferrous metals, non-metal materials and their finished parts.

This tester, the winner of the na- tional quality silver medal prize, can be applied in the factories, scientific research institutes and laboratories of colleges, for de- termining the Rockwell hardness of hard alloys, quenched and unquen- ched steels.

   
MODEL HRD-150 ROCKWELL 
MOTOR-DRIVEN HARDNESS TESTER
MODEL HR-150B ROCKWELL 
HARDNESS TESTER

This tester is a necessary instrument widely used in the fields of machine building, metallurgy and measurement department, for determining the Rock- well hardness of ferrous, non-ferrous metals, non-metal materials and their finished parts.

This tester is designed for use in measuring the Rockwell hardness of hard alloys, quenched and unquenched steels. As its frame is higher than that of conventional type, so that it is a desired instrument for determining the hardness of large- sized workpieces in the factories and repair workshops.

MODEL HSRD-45 SUPERFICIAL ROCKWELL MOTOR-DRIVEN HARDNESS TESTER MODEL XHRD-150 PLASTIC ROCKWELL MOTOR-DRIVEN HARDNESS TESTER

This tester is a necessary instrument widely used in the fields of machine building, metallurgy and measurement and measurement department, for determining the superficial Rockwell hardness value of steel, alloy steel, hard alloy, plated coating, carburized and nitrided layers.  

This tester can be used to deter- mine the hardness of plastic, composite materials and all kinds of friction materials, soft materials, nonmetal soft materials. A specific automatic zeroing dial gauge, an automatic loading and unloading mechanism are adopted in it, so that the measuring accuracy is  high and the performance is re- liable.
     
MODEL HSRS-45 SUPERFICIAL ROCKWELL DIGITAL DISPLAY HARDNESS TESTER   

This tester can be used to determine the superficial Rockwell hardness value of steel, alloy steel, hard alloy, plated coating, carburized, nitrided and cyanided layers. The hardness value measured can be read off the show- window.
