Professional Socket Tester & Outlet Voltage Detector (EU / US / UK)
Take the guesswork out of electrical safety with the QXL HT107D Socket Tester — a compact, plug-and-play outlet tester that instantly checks polarity, grounding, wiring faults, and live voltage on EU, US, and UK sockets. The built-in LCD display gives you a clear, at-a-glance readout in under one second, making it an essential tool for homeowners, electricians, and property inspectors alike.
Made in Mainland China.
Key Features
- Universal Compatibility — Works with EU, US, and UK outlet types; covers operating voltages from 48 V to 250 V / 45–65 Hz.
- LCD Voltage Display — Measures AC voltage 48–250 V with ±(2.0%+2) accuracy so you always know exactly what's coming out of the outlet.
- Polarity & Ground Check — Instantly identifies open ground, open neutral, open live, live/neutral reverse, and live/ground reverse wiring faults.
- RCD / GFCI Function Test — Tests Residual Current Devices (>30 mA, EU/UK plug, 220 V ± 20 V) and GFCI breakers (>5 mA, US plug, 110 V ± 20 V). Note: RCD and GFCI functions do not operate simultaneously.
- Leakage Voltage Measurement — Detects leakage voltage in the 0–99 V / 45–65 Hz range.
- Plug & Play — No batteries required; simply plug in and read the result in one second.
- Portable & Compact — Slim, lightweight design fits in a tool bag or pocket for on-the-go circuit checking.

Frequently Asked Questions
Q: Does the socket tester work with EU, US, and UK outlets?
A: Yes. The HT107D socket tester is designed to work with EU, US, and UK outlet types. It covers an operating voltage range of 48–250 V / 45–65 Hz, making it suitable for a wide variety of international socket standards.
Q: Does the socket tester require batteries?
A: No batteries are needed. The tester draws power directly from the outlet being tested — simply plug it in and the LCD display will show the result within one second.
Q: Can I use the RCD and GFCI test functions at the same time?
A: No. The RCD function (for EU/UK plugs at 220 V ± 20 V) and the GFCI function (for US plugs at 110 V ± 20 V) cannot operate simultaneously. Use the appropriate function for your outlet type.
Q: What wiring faults can the outlet tester detect?
A: The HT107D can identify open ground, open neutral, open live, live/neutral reverse, and live/ground reverse faults, as well as measure AC voltage and leakage voltage — giving you a comprehensive picture of your outlet's wiring integrity.
