PHASE II has launched a new model of the multi-functional Rockwell Hardness Tester: the 900-385, which is capable of measuring Rockwell hardness and surface Rockwell hardness, and can also convert the measured Rockwell hardness values into HB, HV, HLD, HK and σb.
The Rockwell Hardness Tester 900-385 has the following features: ultra-high measurement accuracy, wide measurement range, automatic loading/unloading of test force, digital display of measurement results, automatic printing, RS232 and USB dual communication ports, etc. It is suitable for measuring carbon steel, alloy steel, cast iron, non-ferrous metals and engineering plastics. This instrument is suitable for use in any environment, including: heat treatment equipment, tool magazines, workshops, and testing laboratories.
The indenter protrudes horizontally, and can test surfaces that cannot be measured by ordinary Hardness Testers, such as the inner surface of ring, tubular and frame parts, and the bottom plate
Complete measuring scales: Rockwell HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRH, HRK, HRL, HRM, HRP, HRR, HRS,
There are 15 kinds of HRV scales, surface Rockwell HR15N, HR30N,
HR45N,HR15T,HR30T,HR45T,HR15W,HR30W,HR45W,
HR15X, HR30X, HR45X, HR15Y, HR30Y, HR45Y, a total of 15 kinds of scales, the measured materials cover a variety of hardness ranges,
Such as cemented carbide, quenched steel, alloy steel, mild steel, copper, aluminum alloy, engineering plastics, artificial wood panels, etc
Auxiliary function: upper and lower limit warning settings
Data statistics: find the average, mean square deviation, maximum and minimum values, so that the uncertainty can be directly evaluated.
Hardness conversion, HB, HV, HLD, HK, σb, etc
Automatically corrects the measurement results of surface parts
