DURFICST Circuit Breaker Finder with Dual LCD Display, GFCI Outlet Tester, 90-135V NCV Electrical Circuit Tracer Tool with Buzzer Alarm for Home/Workshop, Includes Carrying Case

Multi-functional Circuit DiagnosticsThe DCT330 integrates a Circuit Breaker Finder, Outlet Tester, GFCI Tester, and NCV Tester, enabling precise circuit breaker location, outlet wiring inspection, and verification of GFCI protection functionality. This circuit breaker finder helps users quickly diagnose common circuit and safety problems in home or commercial environments, making it an efficient electrical diagnostic tool for home repair personnel, professional electricians, and DIY enthusiasts. | Visual & Audible AlarmsThe transmitter (outlet tester) is equipped with a large VA reflective color screen, along with prominent red and green LED indicators, providing the most intuitive visual feedback on test results. The receiver uses a three-color bar graph to visually simulate signal strength, supplemented by a red and green LED status window and a buzzer prompt. When approaching the target circuit breaker, it will trigger a synchronized sound and light alarm for accurate location. | GFCI Outlet TesterThis transmitter can be used as a standalone GFCI outlet tester, automatically completing trip tests with a single button and displaying the trip time. A large LCD screen intuitively displays detailed wiring status, accurately diagnosing six common line faults. The screen also continuously displays real-time voltage (90-135V) to aid in assessing power supply conditions. The built-in battery locks key readings for up to 10 seconds after power failure, ensuring data integrity. | Non-Contact Voltage DetectionThe receiver features built-in non-contact voltage detection (NCV) functionality. Its core principle is to sense the electric field generated around AC power lines, providing a rapid warning of a nearby live conductor through both audible and visual alarms without any physical contact. This function allows users to perform a quick and safe "pre-scan" before any electrical operation, establishing the first line of defense for electrical safety. | Package List1 transmitter (GFCI outlet tester), 1 receiver, 2 AAA batteries for the transmitter, 2 AA batteries for the receiver, 1 screwdriver, 1 carrying case, 1 user manual.
