INNOVATEST designs and manufactures, primarily, load cell based, closed loop hardness testing machines. To understand the great advantages of the closed loop systems over dead weight systems, particularly in hardness testers, one should understand the difference between both systems.
Another key component in hardness testing technology is the Optic or vision system. Optics are often the root cause of limitations in the hardness testing field. INNOVATEST Engineers have developed the most advanced optical imaging systems for Vickers, Brinell or Universal machines, but for less demanding markets we do offer highly advanced analogue and electronic microscopes to address these limitations.
