UNI-T UT25CL Cable and Wire Tester with Socket Tester

Tracking down the right circuit breaker or diagnosing a faulty wall socket can be a tedious trial-and-error process. The UNI-T UT25CL combines a circuit breaker finder, wire detector, and socket tester in one handheld unit, helping electricians and homeowners quickly identify circuits and check wiring status without guesswork.

Who is it for

This tool suits electrical contractors, maintenance technicians, and DIY users who need a reliable way to locate breakers, verify socket wiring, and detect live wires behind plaster or conduits. Its clear LED and buzzer feedback works even in noisy environments.

Main features

• Combined circuit breaker finder, wire detector, and socket tester in one device.
• Detects voltage in the range of 90V to 250V AC, covering standard household and commercial power systems.
• Three detection methods: inductive circuit breaker location, contact socket testing, and non-contact voltage (NCV) detection.
• Socket test identifies live/neutral/earth status, missing earth, reversed polarity, and other common wiring issues.
• Built-in flashlight on the receiver makes work easier in dark panels or under cabinets.
• Auto power-off after approximately three minutes conserves battery life.
• Low battery indicator warns when the 9V battery needs replacement.
