Franck Hertz Experiment Machine (Sigma-396-fhe)

We are manufacturing and supplying a best collection of Franck Hertz Experiment Machine (SIGMA-396-FHE which proved that the energy transferred from electrons to atoms always has discreet values and the values obtained for energy levels are in agreement with spectroscopic results. Thus experimentally proving the Bhora s Model. It is a landmark experiment and can e performed in any college lab.

The experiment consists of the following :-

1. Argon filled tetrode
2. Filament Power Supply 3.6-4.3 continuously variable
3. Power Supply for V G K 1 1.3-5V continuously variable
4. Power Supply for V G A 2 1.3-15V continuously variable
5. Power Supply for V G K 2 0-95V continuously variable
6. Saw tooth waveform for CRO display
Scanning Voltage :0-80V
Scanning Frequency : 115+20 Hz
7. Multirange Digital Ammeter
Display : 3A digit, LED
Range : 10-7, 10-8 & 10-9A

The instrument can not only lead to a plot of the amplitude spectrum curve by means of point by point measurement, but also directly display the amplitude spectrum curve on the oscilloscope screen. This instrument can thus be used as classroom experiment as well as for demonstration to a group of students.
