Richardson’S Dushman Equation Kit

In built low tension (L.T.) supply 0-6V (DC) adjustable for filament heating & High tension (H.T.) supply 0-300V (DC) adjustable for anode voltage, independent variable knobs are provided for L.T. & H.T. adjustment. 

Four analog meters MO65 are provided to read filament current in  (Milliamperes) filament voltage in (Volts), plate voltage in (Volts) & plate current in (Milliamperes).

Circuit is clearly marked on the front panel for the ease of experiments.

Separate tube socket for connecting thermionic diode (Vacuum tube) is provided on the front panel. The whole system is enclosed in metal cabinet.

Kit is used to determine the work function of cathode material.
