Product Features

Swift, straightforward wiring evaluation – Attach the tester to a standard UK 3‑pin outlet; the red LEDs scroll quickly, and the LCD delivers an unambiguous reading of one of six conditions: proper wiring, earth missing, neutral missing, live/neutral reversed, live/earth reversed, or reversed with missing earth.

Dual readout of voltage and frequency – In addition to fault identification, the digital display presents the real‑time supply voltage (90‑250V) and line frequency (45‑65Hz), helping you spot abnormal power variations.

Leakage protection validation – Insert into a correctly grounded socket, then press the RCD test button for under 3 seconds. A healthy RCD will trip without delay. If it remains engaged, the protective device is compromised – contact a professional electrician for immediate service.

Precision and stability – Offering a voltage accuracy of ±(2%+5) and reliable operation across a wide temperature/humidity range, this unit delivers professional‑grade performance for both experts and DIY enthusiasts.

Hassle‑free usage – No configuration needed; the plug‑and‑play design makes it accessible to anyone. The illuminated screen stays clearly visible even in bright conditions, and the compact shape slips easily into your pocket or toolkit.

Multiple everyday uses

Electricians: perform a rapid whole‑house check in about 30 seconds per socket.

Frequent travellers: confirm outlet safety in UK‑standard hotels abroad.

Project supervisors: inspect and sign off on electrical installations with confidence.

Essential safety notes – Always visually examine the tester for damage prior to operation. For RCD tests, switch off all loads on that circuit to prevent accidental interruptions. Any identified fault should be corrected solely by a qualified electrician.
