1. A device for monitoring a number of cycles of autoclaving to which an instrument is subjected, comprising:

  • a) a ferromagnetic magnetizable material member having a prescribed magnetic flux density, the magnetizable material attachable to an instrument;

    b) an electrical conductor winding around the magnetizable material member and connected to a source of electric power to re-magnetize the magnetizable material when the flux density of the magnetizable material has been reduced in an autoclave cycle;

    c) sensor means operatively associated with the magnetizable material member for measuring the magnetic flux density of the magnetizable material member;

    d) computer means for receiving signals from the sensor means when the magnetic flux density of the magnetizable material member has been reduced;

    e) the computer means including memory means for storing data received from the sensor means indicative of said number of cycles.
