Proster Voltage Tester, Upgraded Socket Tester Non Contact Pen and Plug kit with LED Flashlight Pre Installed Battery Sound Light Alarm

【2-in-1 Socket & Voltage Tester Kit】--- Includes a UK plug-in socket tester and a non-contact voltage (NCV) pen — one box covers wiring checks and live-wire detection for home DIY, landlords and electricians doing occasional checks. No need to buy two separate tools 【Non-Contact Voltage Pen, 12-1000V, 3 Levels】--- The pen detects AC 12-1000V (high) / 48-1000V (low) across 3 sensitivity levels via the S-button, with sound + LED alarm and a built-in torch for dark corners. Pen rated CE CAT III 1000V / CAT IV 600V for safer checks 【RCD/GFCI Socket Tester with Voltage Check】--- Plug into any UK socket to verify correct wiring and trip the RCD/GFCI with one button (>30mA). It measures 48-250V AC and shows the state on clear LED patterns — visual only, no sound 【Pen Sound & LED Alarm — Socket Is Visual】--- Only the NCV pen beeps and flashes; the socket tester indicates by LED patterns, not sound. So you get audible confirmation on live wires yet a silent, glanceable read on the wall socket 【7 LED Wiring Patterns, Easy to Read】--- The socket tester flags Correct, Open Ground, Open Neutral, Open Live, Live/Neutral Reverse, Live/Ground Reverse and missing-ground faults — each clearly labelled on the unit, so beginners can diagnose a socket at a glance
