Electrical Problem Checker: Our outlet tester is designed for standard 3-Wire and GFCI-protected 90-250 Volt AC outlets. Whether you’re a professional electrician or a DIY enthusiast, it helps you quickly and accurately detect socket wiring failures. Simply plug it into the outlet, and the LCD screen and the indicator lights will immediately display the results.
Clear Color LCD Screen: Equipped with a vibrant color LCD display, our outlet tester provides an at-a-glance indication of whether the outlet is wired correctly (Green for good, Orange for wiring problems). This intuitive design allows you to quickly and easily read receptacle wiring and voltage measurements. Additionally, it displays the actual voltage of each tested outlet.
Easy to Use: Operation is simple–just plug the tester into the outlet. The clear LED indicator ensures results are easily readable even in dark environments, helping you quickly identify one of the six common wiring issues. Even non-professionals can easily check the voltage and wiring status with this user-friendly device.
One-Click GFCI Tester: Press the GFCI button to check if the trip breaker is functioning correctly. If the GFCI receptacle trips, it indicates that the power leakage protection is working properly. Be cautious when using this function on regular receptacles, as it may cause the household wiring system to trip. Ensure the GFCI test is performed correctly under proper wiring conditions with a current greater than 5mA.
Safety Certificate & Service: This outlet tester conforms to CAT.II 300V and CE certification standards, ensuring safety and reliability. It comes with a one-year guarantee, making it an essential tool for maintenance personnel, inspectors, and homeowners.
