Affri Manual Rockwell Hardness Tester – 250DRM

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.

Description

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 levelled.

 

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.
