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 D
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:
1) electrically using electric field of the built-in plate
capacitor, or 2) magnetically using external Helmholtz
Coils D. Also determine the fundamental electron chargeto-
mass ratio (e/m) and study mean electron velocities
using field cancellation.
Other equipment for use with the Teltron tubes:
605-006 EHT Power Supply
261-031 Digital Meter with two shunts included
231-080 Shrouded Test Lead Red
