LMV-50V Automatic Micro/Macro Hardness Tester Fully Automatic Multi-Vickers Hardness Testing System with Load Cell Technology
Step up to the most versatile and advanced Multi-Vickers Hardness Testing System LECO has ever offered—the LMV-50V
• Two Load Cells for Better Repeatability • Wide Load Range—10 gf to 50 kgf • Customizable Load Ranges Utilizing state-of-the-art, closed loop, selfcompensating load cell technology, the LMV-50V is designed with a user-friendly interface to provide you with the ultimate in flexibility for your materials testing applications. The LMV-50V can perform Vickers/Knoop/Brinell (light load) testing and fracture toughness. The tester loads at the touch of a finger (no knobs to turn for changing loads). The chances of operator error are virtually eliminated. Simply select the desired load on the touch screen, and the LMV-50V does the rest.
Automatic turret head for added convenience
In addition to providing you with all of the standard micro/macro test loads, the LMV-50V also allows you to create a customized test using the free load option—ideal for research applications.
