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