VP 500 Vibroskop-Titer Tester Single Fiber Fineness Tester
  • VP 500 Vibroskop-Titer Tester Single Fiber Fineness Tester

    • The VP 500 researched and developed by LENZING is well-known in the world for its accuracy, flexibility and ease of operation.
    • The test adopts one-button operation, the test result is reliable and correct, and it can be used in connection with the tensile tester VN 500.
    • This instrument has become a global standardized instrument for testing fiber fineness, and conforms to ASTM, BISFA, ISO and DIN international standards.

    • Detection principle:

      One end of the fiber is attached with a corresponding pretension, and the other end is suspended in the test chuck. When the test unit releases current to make the fiber vibrate, the amplitude of the fiber will be recorded by the test unit to calculate the linear density of the fiber. The test process is about 1-3 seconds .
