In the ZHU250CL hardness tester the latest close loop technology is used for applying test forces . The closed loop control system is designed to have a much lower signal-to-noise ratio than a traditional load cell, thus providing much greater consistency of test force application. The accuracy on all loads beats the requirements according to the relevant ISO and ASTM standards.
The extremely wide test force range of 4.9 N to 2.45 kN (0.5 kg to 250 kg) enables testing according to Vickers, Knoop, Rockwell and Brinell to ISO 6507, ISO 4545, ISO 6508, ISO 6506 and the relevant ASTM standards.
