Description

The 3B Scientific U19153 Teltron Tube is a high-vacuum electronic device designed for scientific demonstration. This fluorescent tube utilizes electronic cannons with a divergent, protector, and Cross of Malta configuration. It is specifically used to provide evidence of the flat knitting machine spread of electrons in space free of field. By projecting a half shadow of the Cross of Malta onto a fluorescent screen, it serves as an effective tool for introducing students to the principles of electronic optics.

Key Features

The 3B Scientific U19153 Teltron Tube features electronic cannons with a divergent, protector, and Cross of Malta design for physics demonstrations.

This high-vacuum fluorescent tube allows for the observation of electron spread in space free of field through projection on a screen.

Technical specifications include a heating voltage of 6.3 V AC and a maximum metal voltage of 5000 V.

The device operates with a metal power of approximately 0.1 mA at 4000 V for precise scientific applications.

Designed for educational use, the unit has a total length of approximately 260 mm and an accessory diameter of approximately 130 mm.
