The Socket tester is an essential tool for buyers concerned about electrical safety. It ensures the polarity of power socket wiring and checks the reliability of ground fault circuit interrupters (GFCIs) and residual current devices (RCDs). With quick and accurate detection of socket wiring conditions, it guarantees the safety of socket lines in various settings like homes, offices, and commercial buildings. Whether you need to inspect residential safety or perform electrician installation and maintenance tasks, this device is the ideal choice. Please note that the RCD and GFCI functions operate independently.Features: Functions: Socket polarity test, ground fault circuit interrupter (GFCI), and residual current device (RCD) examination LED red light test result indicator Clear test result reference table seen in the unit Handheld pocket-size tester Specifications: AC voltage: 90~230V( +10% / -15% ), 50Hz/60Hz Working Environment: 0℃~ 40℃; 20%~75% RH Storage Environment: -10℃~50℃; 20% ~80%RH Altitude: ≤2000m Set Come with: 1 x Socket Tester English Instruction Manual Standard factory packaging
