Universal Dynasonic Portable Digital Hardness Tester Supports UCI and LEEB Testing Methods
Product Introduction:
At present, there are kinds of methods for hardness measurement, commonly used like Brinell, Rockwell, Vickers, Leeb, etc, while the disadvantages are obvious for above hardness measurement methods.
Rockwell and Brinell with heavy loading force and big indentation, lead to serious destructive on sample surface.
Vickers apply optical measurement, but only professional technicians can smoothly operate, impossible to measure hardness of heavy work piece, installed machinery and permanently assembled parts.
Leeb hardness tester apply rebound and indirect method to measure hardness, easily lead to big deviation when convert to Birnell, Rockwell and Vickers scales.
SU-200 is a combined portable hardness tester which integrated the ultrasonic hardness testing method and dynamic Leeb hardness testing resolution in one instrument.
SU-200 is updated product based on ultrasonic hardness tester SU-100 and Leeb hardness tester SH-500, it has full of functions of SU-100 and SH-500, so it supports all of static ultrasonic measuring probes and Leeb dynamic impact devices together.
UCI method apply ultrasonic contact impedance method to do comparative hardness measurement for testing pieces, with advantages of high accuracy, efficiency, portable and easy operation.
Widely used to measure hardness of small forgings, cast material, weld inspection, heat affected zone, Ion-nitrided stamping dies and molds, forms, presses, thin walled parts, bearings, tooth flanks, etc.
Leeb method is a dynamic hardness test method using a calibrated instrument that impacts a spherically shaped carbide ball or diamond tipped body with a fixed velocity(generated by a spring force) onto a surface of the material under test. The ratio of the rebound velocity to the impact velocity of the impact body is a measure of the hardness of the material under test.
Leeb method used to test hardness of Die cavity of molds, Bearings and other parts, Failure analysis of pressure vessel, steam generator and other equipment, Heavy work piece, The installed machinery and permanently assembled parts,Testing surface of a small hollow space, Material identification in the warehouse of metallic materials, Rapid testing in large range and multi-measuring areas for large-scale work piece.
