UNI-T UT25A: AC Circuit Breaker Finder & GFCI Outlet Tester (90-120V) with Adjustable Sensitivity

Effortless circuit tracing with the UNI-T UT25A

The UNI-T UT25A combines a circuit breaker finder, a transmitter, a receiver, and a GFCI outlet tester into one compact kit. It’s designed for use on energized 120V systems, offering practical features that help you identify the correct switch quickly and safely.

With the ability to identify circuits on standard 90-120V AC panels, this tool adapts to your environment. The receiver’s sensitivity can be dialed to a very low setting, ensuring it flags the target breaker promptly when you are near the correct panel. When you increase sensitivity, you may notice a clearer alarm confirming your finding. The LED indicators provide at-a-glance feedback, helping you confirm status without guessing, which can be especially useful in busy or dim workspaces.

Key capabilities at a glance

• AC compatibility: Identifies breakers on energized 90-120V systems, suitable for standard residential and commercial panels.
• Adjustable sensitivity: Start at the lowest setting to reduce false alarms, then refine to locate the target breaker with confidence.
• GFCI tester function: A transmitter plugged into an outlet or fixture and a receiver scanned across the panel to verify protection and wiring.
• LED status indicators: Clear visual cues on the transmitter help avoid misoperation and speed up testing.
• Guided use: Step-by-step cues inside the device help you approach the correct switch and verify with a stronger alarm.
• Portable storage: An EVA tool case keeps the components protected and easy to carry between jobs.
• What you get: 1x Receiver, 1x Transmitter, 1x User Manual, 1x EVA tool case — note that the tester may beep more in certain areas, which is normal.

Real-world use scenarios

Whether you’re renovating a space, upgrading an electrical panel, or conducting routine maintenance, the UT25A aims to simplify the process. The combination of a live circuit finder and GFCI testing capability can help you quickly confirm which breaker governs a given outlet, fixture, or circuit, reducing guesswork during troubleshooting and installation tasks.

The tool’s design emphasizes portability and ease of use. The included EVA case makes it simple to store and transport your kit, so you can bring it to job sites, client sites, or your workshop with minimal setup. The balance of a compact receiver and a straightforward transmitter means you can work through panels without extended downtime, while the beeper and flashing LED offer multiple feedback channels to suit different environments.
