Phase II+ Rockwell / Superficial Hardness Tester w/ Analog Display - Digital - 900-385


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 convert those values of Rockwell hardness into HV, HB, HK, HLD and σb values.

The PHASE II 900‐385 is loaded with features such as ultra precise measurements, automatic main test force loading/unloading, digitally displayed results, automatic printing, wide measuring range, and RS232&USB output. The PHASE II 900‐385 is suitable for hardness testing on carbon steel, cast iron, alloy steel, non ferrous metal and engineering plastics. A perfect performer suited for any environment including heat treat facilities, workshops, tool rooms, laboratories and inspection labs. Lifetime technical support is included with all Phase II Hardness Testers.

Phase II+ Rockwell / Superficial Hardness Tester w/ Analog Display
  • The indenter design is ideal for testing inside diameters and recesses, often impossible with more traditional hardness testers. Inside diameters as small as 1‐1/2‐inches 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, 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.
