Voltage Tester, Dual Scale 12-1000V / 48V-1000V, Non-Contact Electrical Tester, Voltage Pen Indicator with NCV, Disconnect Detector with Flashlight and Audible Alarm

Non-Contact Voltage Tester Used to identify live and neutral wires, detect broken wires, and detect the presence of AC voltage. The voltage tester is equipped with an NCV probe that reliably and safely distinguishes between live and neutral wires. Simply place the device near a power outlet, power supply, or insulated cable. The device can be used to test AC voltage in cables, wires, power outlets, household circuits, lighting fixtures, switches, and tamper-proof sockets. Dual Testing Range High sensitivity mode (measuring range 12~1000V AC) and low sensitivity mode (measuring range 48~1000V AC). Suitable for various voltage ranges. The slow movement of the NCV sensor along the AC line can be used to quickly detect circuit on/off conditions and locate circuit breaks. Visual and Audible Warning: If AC voltage is present at the measurement point, the voltage tester's screen turns red, the identification probe illuminates red, and an audible signal sounds. As the voltage increases, the frequency of the red light and the warning signal increases. Easy to Use: The mini size is easy to carry; you can put it in your pocket. The double-insulated plastic exterior and rugged case provide added peace of mind during use. It is also equipped with a flashlight for testing circuits in dark environments. The device automatically shuts off if not used for 5 minutes.
