Product Description
Phase II PHT-6000 Series Portable Hardness Tester

    PHT-6000 Series Portable Hardness Tester for UCI (Ultrasonic Contact Impedance & Dynamic Impact (Leeb) hardness testing
    MEASURING METHOD: UCI & Leeb
    There are two basic methods of portable hardness testing that is accepted in the
    field today.
    “Ultrasonic Contact Impedance" is based on a 136 degree diamond at the end
    of a vibrating rod being depressed into the test surface at a fixed load. The
    difference in Ultrasonic vibration frequency is then calculated into a hardness
    value. The UCI test procedure is slower than the Dynamic Impact style, however
    the “UCI" method of hardness testing is portable, easy and accurate. It also has
    its own advantages when utilized for certain testing applications. UCI testers are
    not restricted to large mass items like dynamic type testers. These units can test
    metals as thin as 1mm and at a hardness value as low as 20HRC (75HB). They
    also excel at performing hardness tests on larger, harder metals as well. Another
    reason for the rise in popularity is due to the fact that the UCI method is
    categorized as “Non?Destructive". That translates into less scrap parts/ lower
    mfg costs due to necessary inspections.
    “Dynamic Impact" is based on the Leeb principle of hardness,developed by
    Dietmar Leeb in the 1970’s. A spring loaded impact body is thrust to the test
    surface, effecting rebound. The speed of both the initial thrust and the rebound
    is measured in a non?contact mode. This is calculated as a Leeb hardness value
    and then automatically converted to Rockwell C, B, Brinell, Vickers and Shore
    Values. It has effectually brought easy, fast and accurate results to portable
    hardness testing.
