AFFRI Universal Hardness Tester LD750 / LD250

ONE INPUT FOR THE ENTIRE TEST CYCLE

The hardness tester’s head moves down until contact is made, clamps the piece, applies the force and make the indentation. The software will move to the camera view mode where the indent is automatically measured.

CLOSED LOOP TECHNOLOGY (PAT. AFFRI)

Load forces are applied through load cells and controlled in "Closed Loop" with a frequency of 1 khz, assuring perfect linearity in every range. Results are not affected by any structural deflection, misalignment or vibration.

MOTORIZED TESTING HEAD

Automatic movements with automatic stop when contact is made. Up to 300 mm of motorized vertical stroke. The approach of the head to the peace and not the opposite allows more accurate, scable and safe measurements.

CLAMPING SYSTEM (PAT. AFFRI)

Secure contact with the specimen is always maintained, even in the unlikely event of any specimen movement during the operation cycle. The clamping system assures complete stability of any test piece throughout the test cycle, even if it's oiled, rusty or dirty.

MOTORIZED TURRET

One slot for an indenter and one slot for an objective. Auto-rotating and auto-tool-switching for a complete automatic measurement cycle.

SOFTWARE

The preinstalled software controls the whole instrument avoiding setting errors or operators mistakes: Powerful software for test cycle managing and automatic indent reading. Wide settings parameters for measurement setup, image adjustments, statistics and data storage.
