UCI probe application of the UCI Hardness Tester NOVOTEST T-U2
Ultrasonic hardness testers NOVOTEST T-U2 is recommended for measuring of hardness of objects with complex geometrical shape (gear teeth, saw blades, various metal fasteners, etc.), with small (over 10 grams) mass (ironwares, etc.) and thin walls (thicker than 1 mm), in those cases, when application of Leeb probe is unsuitable or requires to perform additional operations.
The ultrasonic contact impedance (UCI) probe of UCI Hardness Tester NOVOTEST T-U2 is used for measuring the hardness of small items, objects with thin wall, complex form, and to measure the hardness of surface hardened layers.
For hardness testing of flat objects user has to use the nozzle with a rubber ring for preventing displacement of the probe during testing.
For testing the objects with round surface, user has to upend the nozzle with special recesses.
For hardness testing of small items and objects
with complex form, user can use probe without nozzle.
UCI Hardness Tester NOVOTEST T-U2 allows user to calibrate it for any metal materials and make tests on any hardness scales, in this case user has to calibrate device on test blocks of such material with different hardness values, which were obtained from hardness testing with bench hardness testers, which use direct method of hardness testing.
Also, portable hardness testers NOVOTEST are available with two probes in set: UCI and Leeb. In case of using combined portable hardness testers NOVOTEST T-UD2 or T-UD3, user benefits from two methods of measurement – it is the maximum that can be obtained from a portable hardness tester.
So, portable UCI and Combined hardness testers NOVOTEST are a good alternative for bench hardness testers and can solve almost any of the same tasks, as bench hardness testers would.
