Socket tester, a professional power supply polarity test and phase detection tool, and both leakage switch detection function. It uses high-precision sensing technology to quickly and accurately judge the polarity state and phase of the power socket, effectively preventing electrical safety hazards. Lightweight and portable design, suitable for home, office and all kinds of electrical work environment, is your electrical safety inspection ideal choice. Socket test: Comprehensively test whether the functions of the socket are normal, including jack contact, load capacity, etc., to ensure the safe use of the socket. Power polarity test: accurately determine the position of the live line and neutral line of the power socket to avoid safety hazards caused by reverse connection. Phase detection: Detects the phase relationship of three-phase power to ensure that electrical equipment is correctly connected to the power grid and prevent equipment damage or safety accidents caused by phase errors. Leakage switch test: simulate the leakage situation, test the sensitivity and accuracy of the leakage switch, ensure that the circuit can cut off the power supply in time when leakage occurs, and protect personal safety.
