The ETB-198 trainer is a specialized experimental setup designed for the determination of the work function of tungsten and the verification of Richardson’s equation, which explains thermionic emission. This setup enables students and researchers to investigate the emission of electrons from a heated tungsten filament and verify the theoretical relationship between current density and temperature.

The trainer includes:

  • A high-vacuum diode tube with a tungsten filament

  • Built-in regulated power supply

  • Digital meters for accurate voltage and current measurement

  • Well-labeled test points and control switches for safe experimentation

The ETB-198 is ideal for advanced physics laboratories, particularly in the field of solid-state physics and thermionic emission studies, offering hands-on understanding of fundamental electron behavior in metals.
