The MRS 250 is a top-level bench hardness tester for shop or lab applications.

  • Fully motorized for fully automatic test cycles
  • Absolute accuracy (better than 0.5%) in every condition
  • Load forces are electronically controlled in Closed Loop
  • Digital hardness tester with LCD screen, user friendly interface, real time statistics

One button measurement

Push the start button and the head moves down performing the hardness test cycle in automatic sequence.

Motorized vertical stroke

The MRS measuring head is fully motorized with a vertical sliding stroke of 2" (50 mm). When testing unstable samples or deflective parts, the measuring head will follow the sample without losing contact.

Load cell and closed loop technology

Load forces are applied through load cells and electronically controlled. Accurate measurements, even on the first test, eliminate the need for multiple tests. There is no need to perform a second test, the first one is precise.

L.I.S.A. - Laser Indicator System

Exclusive application which allows ultra-precise test positioning. It can reach extreme points with lack of illumination, i.e., edges of gear's teeth, or sides of cutting tools vand blades.

Extreme Precision

The 250 MRS hardness tester guarantees maximum reliability even in bad conditions. The tester features allow for correct results even if the piece is badly positioned. The measurement is not compromised if the piece is dirty with oil or dust.

Clamping System

Secure contact with the specimen is always maintained thanks to the protected indenter and supporting base. The clamping system assures perfect stability of any test piece throughout the test cycle, it moves with the head for the whole vertical stroke generating a constant pressure.

Protected Indenter

The indenter is protected and retracted, it only moves down after the specimen is fully clamped and stable, minimizing the risk of accidental indenter damages.

Working Base

Vertically sliding chromed worktable capable of bearing masses up to 4,400 lbs. (2000 kg.) which allows for steady hardness measurements. It is possible to install different types of part support anvils: from large plane tables to “V” shaped anvils or special solutions for irregular specimens.
