Franck-Hertz Hg-tube
Article No: 09105-10
The Hg tube on the plate is used for recording the Franck–Hertz curve. It is a replaceable high-vacuum tube filled with mercury, which evaporates when the tube is heated in a heating oven. Plane-parallel electrode system to avoid field distortions Indirectly heated oxide cathode with long service life Easy connection via a multi-connector for fast experimental setup Simple automated experiment execution using the power supply unit (09106-99) and software Clear visualization of the setup via the circuit diagram printed on the housing Technical Specification Heater: 0–7 V, max. 150 mA Grid voltage: 0–60 V Retarding voltage: 0–3 V Operating temperature: (175 ± 10) °C Tube dimensions (mm): l = 130, d = 28
