UH930 Universal Hardness Tester
The Universal Hardness Tester UH930, with its user-friendly operator panel, displays hardness values for all common hardness test procedures. The closed-loop load system eliminates overshoot and combines a fully-automatic controlled test cycle with a wide load range from 1 - 250 kgf. The quick navigation buttons allow operators access to 99 different test programs for all hardness scales (HR, HB, HV). Each program can be set up with user-defined test parameters, including test force, application time, conversion, and shape correction according to ISO standards.
Intuitive user interface and one-touch operation ensures an efficient and reliable hardness test process. The interchangeable objectives, ranging from 20x - 140x, provide a wide application range.
