250 DRM

Motorized rockwell hardness testers for simple use

Rockwell Hardness Tester 250DRM is a semi-automatic and simple hardness tester HRC, HRB, HRA and other scales, with test loads from 3 to 250 kgf. It works with Rockwell, Superficial Rockwell and Brinell HBWT hardness tests conforming to all hardness testing standards including ASTM E10 – E18 and ISO 6506 – 6508.

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 through 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.

206 EX

Semi-automatic hardness tester for simple measurements

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.

205RT hardness tester, how does it work?

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 act on the lever to get result. 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.

EXTRA FEATURES

L.I.S.A – Laser Indicator System Affri (Patented)

Exclusive application which allows ultra-precise test positioning. The dual laser pointing system helps to define the indentation area and distance before the contact between the indenter and the specimen. Reach extreme points with lack of illumination, edges of gear’s teeth or sides of cutting tools and blades. (This application is optional)

SAMPLE ILLUMINATION BY LED

Adjustable LED light source for a clear view of the test zone on any surface or specimen shape. Illuminate extreme points where lighting is low like sample holes and dark layers. The adjustable arm of the light can be bent in any direction allowing illumination outside of the testing area. (LED light is optional)
