Apparatus is designed to work on mains 230V, AC Low voltage variable DC power supply unit built-in,three analog meters are provided for anode voltage/current and solenoid current. Solenoid unit is mounted on a wooden horizontal base so that magnetron can slide in solenoid pipe. Complete in all respects. To determine specific charge of an electron using Magnetron Valve Method (Short Solenoid Method).
