SKU: 250DRM
Description
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
