Rockwell Hardness Tester DRM RT EX

250 DRM - 206 EX - 206 RT

Semi-automatic hardness testers for Rockwell, Superficial Rockwell, Brinell and Vickers hardness test methods in compliance with ASTM and ISO standards. DRM, EX and RT are low cost 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, pull lever/ push button and within seconds results appear. Load forces are applied through a load cell system which eliminates problems associated with dead weight systems on traditional testers: not affected by vibration and no need to be leveled; work in any condition, even inclined, due to the Affri System where load forces are directly applied along the indenter's axis, without ratios and levers. Hardness testing on all metals: iron, steel, tempered steel, cast iron, brass, aluminum, copper and metal alloys. Heat treatment, hardening, nitriding, cementation and hardfacing.

Automatic motorized hardness tester:
250 DRM 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 push the start button activating preloading and loading in automatic succession; within seconds results appear. Load forces are electronically applied throug 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.
 
Main control LCD panel in front of the measuring head for setup of test parameters:
Selection of hardness scales, dwell time, conversion data, return stroke, memory and storage of results, statistics, test temperature measure, calibration, system checkup, tolerance range, in-time results average, correction of round surface and automatic evaluation.

Rockwell Hardness Tester 
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.
 
Large LCD and lots of function. 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. Touch key pad board IP 64 protection.
The software controls the whole instrument during the entire cycle avoiding operator errors:

Semi-automatic analogic hardness tester:
206RT 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 push the start button activating preloading and loading in automatic succession. Direct Rockwell reading value is immediately visible on the clear dial gauge and can be converted in other hardness scale methods using Affri conversion tables. 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.
