Ultrasonic Hardness Tester Leeb 918-1
Theory Introduction: UCI Method (Ultrasonic Contact Impedance)
● In order to solve the problems of workbench Vickers hardness tester (Long test time; Bulky and heavy; Not suitable for test on site and test large workpiece; Huge technical demand for the operators), in 1961, Ultrasonic Contact Impedance, a hardness testing method was developed by Dr. Claus Kleesattel, and the hardness tester designed by UCI method is called Ultrasonic Hardness Tester.
● UCI hardness tester uses a spring to generate the test force required for Vickers hardness test, test force is applied to the user's workpiece by means of a resonating rod which is inlaid with a 136 ° diamond regular pyramid indenter, the diamond indenter forms a Vickers diamond indentation on the workpiece. Because of the use of standard Vickers indenter and test force, so UCI hardness tester can test Vickers hardness of workpiece directly.
Features and Functions
● Adopt ultrasonic contact impedance method, test with high precision, fast speed, portability.
● Carried standards: DIN 50159, ASTM-A1038, JB / T 9377, JJG-654, GB\T34205.
● 3.5 inches large LCD screen with 320×480 color graphics dot matrix.
● One-point calibration: adapt to materials with different elastic modulus.
● Multi-point calibration: calibrate various scales and can adapt to composite or new materials.
● Fast test speed, output test results within 2S.
● Memory: 50 groups of data.
● Test in 360° without correction. ( Angle between probe and testing object 90°±5°)
Application Fields
This UCI Hardness Tester With Fast Test Speed can be applied in the hardness testing of below fields:
● Hardness measurement of most ferrous, nonferrous metals and alloys in industrial production.
● Hardness test of flange edge and gear root stamping parts, mold, thin plate, face-hardened gear tooth, gear groove and taper part
● Hardness test of axle and thin-wall pipes and vessels
● Hardness test of wheels and turbine rotors
● Hardness test of bit edge
● Hardness test of welding parts
● Measure the depth of deep hole with certain aperture, concave and convex mark with large radians, and irregular plane
