YG463-II Wang Yanfa Breathability Tester

  • YG463-II Wang Yanfa Breathability Tester

    Instrument usage:
      Suitable for measuring the permeability of lithium-ion battery separators.
    Measurement principle:
      A certain pressure of air passes through the nozzle, and when penetrating the test piece, the impedance generated by the test piece to penetrate the air determines the air pressure between the nozzle and the test piece. Measure this pressure value and theoretically calculate the permeability value equivalent to the number of isolation seconds based on it.
