Buehler, Lake Bluff., Ill., introduces the Wilson VH3300 Vickers/Knoop hardness test system, which expands the range of automatic these hardness testers with a solution tailored to measurements with very high and/or very low test loads. It provides an extensive variety of scales and magnifications, and provides maximum flexibility for automated hardness testing to ASTM and ISO standards.
It is useful in the test laboratory, in materials and product development, in clean production environments, and in routine quality control. It is ideal for the more advanced heat treatment processes that require hardness testing systems to be durable while maintaining precise control during critical test data generation.
The instrument is equipped with the patent-pending collision protection technology, a high-speed sample stage, and the DiaMet universal testing software. It features a six-position test head with up to three indenters and three zoom objectives, an automated X/Y sample stage available in two sizes (180 mm x 180 mm as standard) and a powerful image analysis system. A wide range of test loads from 5 g to 60 kg (depending on configuration) renders the sturdy system suitable for a wide variety of applications.
A purpose-designed collision protection system helps to avoid accidental damage to the indenters and objectives due to operator errors. The VH3300 hardness testing system provides the ultimate high-capacity testing platform capable of performing 150 make-and-measure indents an hour.
A high-resolution digital camera and long working distance objectives, in combination with innovative, calibrated digital zooming capability, provide up to 2000x magnification. The entire system is controlled through the DiaMet hardness automation software, including setting of test parameters, automated indentation and measuring, acquisition of test data, statistical analysis, data export, and a range of other functions speeding up the test procedure and ensuring high-accuracy acquisition and analysis of test data.
