Description
Zodiac Overseas presents a high-precision e/m Apparatus using the Magnetron Valve Method, designed to determine the charge-to-mass ratio (e/m) of an electron. This setup is ideal for advanced physics laboratories and facilitates a clear understanding of electron motion in magnetic and electric fields.
Product Highlights:
- High-vacuum magnetron valve enclosed in a protective housing
- Built-in power supply unit with regulated voltages for anode and filament
- Precision Helmholtz coil (or permanent magnet) arrangement to generate uniform magnetic field
- Digital or analog readouts for accurate voltage and current measurements
- Compact and modular design for easy demonstration and handling
- Supplied with user manual, circuit diagram, and experiment procedure
Perfect for universities, engineering colleges, and research labs to conduct foundational experiments in modern physics and electromagnetism.
