ZHU topLine hardness testers from the Zwick Roell Group

State-of-the-art universal hardness testing machines use innovative electromechanical technology for high precision testing in a wide range of applications, particularly for quality assurance, production-line testing and in the laboratory.  
Zwick’s three ZHU topLine hardness testing machines are based on optical zoom technology, eliminating the need for frequent lens changes. Closed loop / load cell technology provides solutions for both optical and depth measurement testing in accordance with testing methods.  
Operators will appreciate the intuitive, easy-to-use system. Test sequences can be configured individually, then saved or loaded. In addition to manual indentation measurement, fully automatic image analysis is optionally available, reducing operator influence to a minimum.
