How it's used

This tool is essential for basic electrical safety in Hong Kong homes. It works by touching the metal tip to a wire or contact point while placing a finger on the conductive end cap to complete the circuit, causing a small neon bulb inside to glow if current is present. It is strictly for identifying live wires and should never be used to measure voltage levels.

Examples

The electroprobe is broken, please buy me a new one.

Common mistake

Do not confuse this with a multimeter, which is called 萬用錶. An electroprobe only indicates the presence of voltage and cannot provide specific readings.
