Voltage detectors and non-contact testers.
Voltage detectors check whether wires, sockets, switches and cables are live before you start work, which is an essential safety step for electricians, DIY users and maintenance workers. Non-contact voltage detectors beep and light up when they detect voltage near a wire, without touching any metal. Test pens and screwdriver testers are simple and affordable. Multifunction testers also measure voltage levels and check continuity. Check the voltage range, safety rating (CAT rating) and indicator type before ordering. Always test the detector on a known live source before use to make sure it works. Voltage detectors are small enough to carry in a pocket. They help prevent electric shocks and accidents.
