Portable Socket Tester for EU UK US Outlets

The TaoTao HT107B-US is a compact digital socket tester designed for electricians, technicians and DIY users who need to verify wiring correctness on 48-250V mains supplies. It checks EU, UK and US plug standards with a single handheld unit that fits in a tool bag.

Confirm Local Plug Type and Supply Voltage

Before ordering, verify which of the three plug formats matches the outlets in your workspace and that the local supply operates between 45 and 65Hz within the 48-250V measurement range. The tester includes RCD trip at 30mA for 220V±20V systems and GFCI trip above 5mA for 110V±20V systems, so the correct protection standard must be present.

Continuous Operation Within Rated Limits

Under sustained use the LCD display remains readable in low light while the unit measures voltage continuously across the full 48-250V band with ±2.0%+2 accuracy. Rated for altitudes up to 2000m, the tester maintains its detection performance during extended troubleshooting sessions without overheating or drift.
