  • Teltron Discharge Tubes
    The Teltron range of demonstration discharge tubes
    has been designed to show the properties of the free
    electron.


    The D range is the original Teltron range with connections
    fixed on the tubes. The S range is a newer range with
    connections on the stand rather than the tubes.
    Please note the ranges are not interchangeable.


    Teltron Perrin Tube S
    Highly evacuated electron tube with focusing electron
    gun and fluorescent screen inclined relative to the beam
    axis so that the path of the beam can be seen and the
    effects of electric and magnetic fields can be studied.

    The electron beam can be deflected using two methods:

    • Electrically using electric field of the built-in plate
      capacitor, or
    • Magnetically using external Helmholtz
      Coils S. Also determine the fundamental electron chargeto- mass ratio (e/m) and study mean electron velocities using field cancellation. Instructions included.
