Combining the best
The ZHU250CL hardness tester employs the latest technology, with closed-loop control for test load application. The modern system for test load application (closed loop) stands out because of its precision. Accuracy exceeds the requirements of all relevant ISO and ASTM standards.
For more sophisticated or for automated applications, PC controlled versions are available as semi or fully automatic systems based on the high definition software (HD).
