Original product description
Digital Rockwell H ardness T este r HR -150D HR -150D digital Rockwell hardness tester has high level automation, stable and reliable performance, it is equipped with sophisticated sensors so that can test data more accurate;Large digital LCD screen provide comprehensive data for quality control.
Fe atures: The LCD screen will display hardness value , conversion value, test force, dwell time, indenter info.
etc directly, indicator responses sensitively, show the hardness value accura;Automatic loading - dwell - unloading test force, easy operate Support English & Chinese language, menu structure Built-in printer can print test result directly One-time casted molding shell, stable structure and it is not easy to be out of shape.
It can work under harsh environment;the shell coating adopted car paint technology with white color.
it has strong scratch resistance capability and still look bright as new after use many years;The screw rod adopts the fine grinding process, which ensures that the machine can be lifted smoothly and without eccentricity, make test accuracy more higher and stable.
Working principle of Rockwell hardness test: The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload.
There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, where A is the scale letter.
Main application: Hardened steel, quenched and tempered steel, annealing steel, bearing steel, strip steel, hardened steel sheet, hard alloy, etc.;Technical parameters: Model HR-150 D Rockwell scale HRA,HRB,HRC,HRD,HRE,HRF,HRG,HRH, HRK , HRL , HRM, HRR Conversion scale HRA, HRB, HRC, HRD, HRF, HV, HK, HBW, H15N, H30N, H45N, H15T, H30T, H45T Test force Initial:10kg(98N);Main:60.
