INSTANT WIRING CHECKS — Plug directly into any UK 3-pin socket; three LED indicators read out the wiring condition in seconds — no tools, no probes, no electrical knowledge required. IDENTIFIES COMMON FAULTS — Detects correct wiring, missing earth, missing neutral, and live-earth or live-neutral reversal — the faults most likely to appear in older wiring or DIY socket installs. AUDIBLE BUZZER ALERT — Buzzer sounds alongside the LED pattern on a detected fault, so you don't have to memorise the light codes to know something's wrong. COMPACT & PORTABLE — Small enough for a tool bag or glovebox; ergonomic grip makes it easy to plug in and read one-handed. CAT II 230V RATED — Built for safe use on standard UK domestic sockets, with a durable housing for everyday site or home use.
