Description
Key Features
The 3B Scientific U19157 Teltron Triode is filled with low-pressure helium gas for specialized scientific investigations.
This electron tube contains a thermionic cathode, control grid, and anode to support physics experiments.
Use this device to record the current-potential (IA-UA) characteristics of a thyratron during quantitative studies.
Observe the discharges and discontinuous energy release of helium atoms during inelastic collisions with free electrons.
The unit supports a maximum heater voltage of 7.5 V AC/DC and a maximum anode voltage of 500 V.
This model provides an anode current of approximately 10 mA at 200 V for consistent laboratory results.
