Digital hardness testers for Brinell and Vickers test method in compliance with ASTM, ISO and JIS hardness standards. Load range from 10 to 3000kgf.
LD 3000 hardness testers are low cost bench hardness testers with high accuracy standards. Easy to use, single start button for the entire test. Load forces are applied through load cells and controlled in "Closed Loop" with a frequency of 1khz, assuring perfect linearity in every range. Hardness tests on all metals: iron, steel, tempered steel, cast iron, brass, aluminum, copper and metal alloys.
EASY AND FAST AUTOMATIC MEASUREMENTS:
Spin the leveling screw’s handle and bring your sample to make contact with the clamping hood locking the piece. Press the START button and the measuring head approaches the sample, applies the load to perform the indentation and returns up in automatic succession without breaching a phase.
•CLOSED LOOP TECHNOLOGY(Pat.AFFRI):Load forces are applied through load cells and electronically controlled in “Closed Loop” with a frequency of 1khz, assuring perfect linearity in every range.Results are not affected by structural deflection,misalignment, vibration or problems associated with dead weight systems on traditional testers.
•SELF CLAMPING SYSTEM (Pat. AFFRI).
When testing unstable samples or defective parts, the AFFRI System will follow the sample and not lose contact, compensating any frame deflection during the test cycle. Accurate results are assured even with oiled, dusty or dirty pieces.
