The ULTRAMATIC 2 is the next generation portable and laboraty use ultrasonic hardness tester.
The instrument covers several new advanced features that can be selected from a menu operated full color display.
One of the major advantages of the CV400 is that it works with a range of probes that allow different test forces.

• Ultrasonic Contact Impedance test principle, fast, accurate, easy to use in confined spaces
• Full color display with easy to operate user interface
• Suitable for hardness tests on metals, plastics, ceramics
• Direct reading in Vickers HV, and direct conversion to HRC, HRB, HB & UTS
• High reproducibility, tolerance within ±1%
• Extensive range of application at locations difficult to access
• Large memory, statistics and multiple data outputs
• Optional dynamic rebound hardness impact devices available
• Windows software for testing, remote control, data processing and file storing
