The ADL-DU110 hardness tester combines two hardness measurement methods: ultrasonic and dynamic. This makes the device a versatile and effective solution for input, inter-operational and output quality control of materials.
The universal hardness tester is used for various tasks. It is well applicable for measuring carbon and structural steels, surface-hardened products, heat-resistant, corrosion-resistant, stainless steels, galvanized coatings, hardfacing, products of complex configuration, thin-walled and compact products.
To measure the hardness of massive products with poorly prepared surfaces and a coarse-grained structure, it is recommended to use a type G dynamic probe.
It has a low sensitivity to product curvature and surface roughness. The device can be equipped with additional replaceable sensors with different dimensions, spring stiffness and indenter stiffness.
With the help of an ultrasonic sensor, it is possible to easily solve the problems of measuring the hardness of grooves, surfaces of small radius, hard-to-reach places, products of complex shape and small parts.
It is well applicable for measuring the hardness of the mirror surfaces of shaft journals, blades, gear teeth, since it has a small imprint of the identifier.
