Feature

●Straight-in cathode ray tube: Demonstrate the phenomenon that the cathode ray moves in a straight line and can be blocked by metal.
●Magnetic field effect cathode ray tube: Demonstrates the phenomenon that the ray is deflected in the magnetic field, indicating that the cathode ray is a charged particle stream emitted from the cathode.
●Mechanical effect polar ray tube: Demonstrates the phenomenon that the cathode ray causes mechanical motion of the object, indicating that the cathode ray has momentum and energy.
●Electrostatic effect cathode ray tube: Demonstrates the phenomenon that the cathode ray deflects in the electric field, which proves that the cathode ray is a negatively charged particle stream (ie, electron flow).
●Scope of application: Teachers teach in laboratory classrooms to increase students interest in physics and electricity


Description

Structure
Directly enter the magnetic effect The cathode ray tube is composed of a bulb, a baffle plate, a fluorescent plate, a cathode, an anode, a bakelite seat and the like.

Demonstrate environmental conditions
1. The relative humidity is not more than 80%.
2. Temperature -101.---40 °C.

Precautions
1. Vacuum glass products, gently handle, pay attention to protect the bulb and prevent gas failure.
2. Do not use excessive force when connecting the electrodes to avoid damage to the instrument.
3, pay attention to the wiring according to the wiring diagram, proofread the power supply voltage, check the error can be demonstrated.
