This mains tester screwdriver is designed for checking the presence of voltage in the 100-500V range. Featuring a 120mm shaft, it provides a practical tool for electricians and general trades for identifying live circuits during installation or maintenance tasks.
It is typically used on-site for basic voltage testing before carrying out electrical work such as replacing sockets, switches, or connections. The slim profile allows access to confined areas within panels or fittings.
