Description:

This instrument is used for proving Bohr's theory of atomic energy level. It takes a tube filled with argon as a F-Htube. The experiment can be done under normal temperature, demanding no heating or temperature keeping. The spectrum amplitude curve can be plotted by means of point-measuring, it can also be observed directly on the screen of oscilloscope.

Details:

1. F-H tube: fill with argon gas;

2. Preheating time: ≤5min;

3. Micro-current measuring range: 10-9~10-6A;

4. Numbers of spectrum amplitude by point-measuring: ≥5;

5. Numbers of spectrum amplitude on oscilloscope: ≥3.
