Digital Rockwell/Superficial Rockwell Hardness Tester
The Phase II state-of-the-art multi-functional 900-385 twin hardness tester can be used directly to measure Rockwell and superficial Rockwell hardness and change those values of Rockwell hardness into HB, HV, HLD, HK, and σb values.
Loaded with features such as ultra-precise measurements, wide measuring range, automatic main test force loading/unloading, digitally displayed results, automatic printing, RS232&USB output, etc., the 900-385 is suitable for hardness testing on carbon steel, alloy steel, cast iron, nonferrous metal, and engineering plastics. A perfect performer suited for any environment, including heat treatment facilities, tool rooms, workshops, laboratories, and inspection labs.
- The indenter design is ideal for testing inside diameters and recesses, often impossible with more traditional hardness testers. Inside diameters are as small as 1-1/2 inches and can be tested with the standard indenter. Operators can test close to vertical surfaces, to within 1/4-inch with the standard indenter. Testing is fast, and accurate, and there are fewer broken diamonds due to an outstanding viewing area.
- Wide measurement range: 30 Rockwell hardness scales in total, HRA, HRB, HRC, HRD, HRE, HRF, HRG, HRH, HRK, HRL, HRM, HRP, HRR, HRS, HRV, HR15N, HR30N, HR45N, HR15T, HR30T, HR45T, HR15W, HR30W, HR45W, HR15X, HR30X, HR45X, HR15Y, HR30Y, and HR45Y.
- Auxiliary functions: The 900-385 rockwell hardness tester is capable of upper and lower limit settings; data statistics, the computing for average value, standard deviation, maximum and minimum; scale conversion (the testing results can be converted into the values of HB, HV, HLD, HK and σb (strength); curved surface correction will automatically correct the measuring results for cylindrical surface and spherical surface.
