The CV-HV400 hardness tester operates using the UCI principle with a Vickers diamond indenter (136°). It supports multiple test loads (3N–98N), providing a wide hardness range from HV10 to HV3000 with ±1% reproducibility. Featuring a large backlit display, 1000-reading memory (expandable to 30,000), RS-232/RS485 interfaces, and statistical analysis functions, it is designed for both laboratory and field testing.
CV Instruments Ultramatic 2 CV-HV400
Engineered for flexibility and precision, the Ultramatic 2 CV-HV400 is ideal for testing materials in difficult-to-access locations. It provides direct Vickers readings and conversions to HRC, HRB, HB, and UTS, making it suitable for a wide range of industrial applications. The instrument supports multilingual operation, multiple calibrations, and optional Windows software for advanced data processing and documentation. With rechargeable batteries, extensive memory, and probe options, it offers both portability and efficiency for quality assurance, research, and production environments.
