Screw Driver, Electrical, With Neon Bulbs

Integrated Safety Circuit: Features a built-in, high-value resistor that limits the current flowing through the user to a safe, imperceptible level, ensuring total safety during testing.

Transparent High-Impact Handle: Constructed from shatterproof, crystal-clear cellulose acetate or polycarbonate, providing $360^{\circ}$ visibility of the neon bulb from any angle.

The Electrical Voltage Tester is an essential first-line safety instrument for any student or technician working with electrical circuits. It features a transparent, high-insulation handle containing a high-quality neon lamp and a current-limiting resistor. When the tip of the screwdriver touches a live conductor (ranging from $100\text{V}$ to $250\text{V}$ ), and the user’s finger touches the metal contact on the butt of the handle, the neon bulb glows to indicate the presence of voltage. This tool allows for the safe identification of “hot” wires and ensures that circuits are de-energized before maintenance or experimental assembly begins.
