This dual fine beam Teltron tube is ideal for advanced physics lessons, allowing students to explore electron behaviour and specific charge measurements in a visually engaging way. Designed for secondary schools and colleges, it provides clear demonstrations of electron paths and gas/electron collisions using neon gas.

• Neon-filled, partially evacuated glass tube with two electron guns (axial and tangential)

• Electron beams visible as fine luminescent paths throughout the tube

• Adjustable beam angle via miniature deflection plates

• Phosphor-coated screen for use with the axial gun

• Technical details: max filament voltage 7.5 V AC/DC, anode voltage 120–300 V DC, max anode current 30 mA, max deflection voltage 50 V DC

• Glass bulb approx. 130 mm diameter; total length approx. 260 mm
