Affri Manual Rockwell Hardness Tester – 206EX

206EX is a semi-automatic and simple hardness tester with test loads from 3 to 187,5 kgf. It works with Rockwell, Superficial Rockwell and Brinell HBWT hardness tests conforming to ASTM and ISO hardness testing standards.


Semi-automatic digital hardness tester:

206 EX is a fast and really easy bench hardness testers with high accuracy standards. To perform the test just act on the elevating screw and bring the sample to make contact with the indenter, then pull the lever activating preloading and loading in automatic succession; within seconds results appear. Load forces are applied through two dynamometric load cells which eliminates problems associated with dead weight systems on traditional testers. It is not affected by vibration and it doesn’t need to be leveled.


LCD and key pad board IP 64 protection:

  • Simultaneous view of 2 scales, the one of the test and the one chosen from the list of conversion scales. Conversion values for all hardness scales HB, HV, HSD, HK, HRN, HRT, N/mm.
  • Precise test settings. Check load applied correctly. Select dwell time. Calibration for direct and indirect method conform to ASTM E 18 ISO 6508. Dynamic results. Simultaneous view of the range of results for statistic. Results average update at the last measure. Statistic CP CPX CX Histogram and number of test corresponding to tollerance values (Lo, Hi, Ok).
  • Unique performances. Temperature measure C° usefull for certificate test conform to ASTM E 18 ISO 6508. Depth of indentation in 0,01 micron. Acoustic signal for dwell time and for preload. Output RS 232C or converter to USB. Back light LCD display 128 x 64 pixel.
