Socket Testers

Socket testers are compact, easy-to-use devices designed to quickly verify the wiring integrity and safety of mains sockets. Ideal for electricians, maintenance engineers, and landlords, they detect common faults such as missing earth, reversed polarity, or live/neutral issues. Many models feature clear LED indicators or audible alerts, making them perfect for fast inspections in domestic, commercial, and industrial environments. Socket testers provide a first-line check before deeper testing or installation work, ensuring safety and compliance. Explore dependable socket testers available now at CEF.
