This experimental setup is designed to determine the ionisation potential of mercury using a gas-filled diode. The kit includes a high-quality power supply, two digital meters for accurate voltage and current readings, and all necessary components assembled in a compact, ready-to-use form.
The principle involves observing the characteristics of the diode in the presence of mercury vapor and identifying the critical voltage at which ionisation begins. This voltage corresponds to the ionisation energy of mercury atoms.
It is ideal for physics laboratories in colleges and universities, especially for curriculum-focused experiments in atomic physics, gas discharge phenomena, and electronic instrumentation.
Key Features:
Built-in regulated power supply
Two digital meters for simultaneous V-I measurement
Clear panel layout and test points
V.V. (Variable Voltage) and C.R. (Constant Regulation) options
Safe and robust housing for student use
