Non-Contact AC Voltage Detector with Adjustable Sensitivity 12-1000V/48V-1000V, Electrical Tester with LCD Screen, LED Alarm Indicator, and 3 Warning Light Modes

【CE CAT III 600V RoHS Voltage Tester】This professional voltage tester features double insulation for safety. A high-voltage alert warns you of voltages exceeding 90V; the screen turns red and a safety symbol illuminates. Perfect for DIY enthusiasts, hobbyists, and homeowners, it helps you perform the first and most important safety check. (Note: Not suitable for testing Christmas lights)
【Dual-Range Electrical Tester】The default mode of the upgraded 2022 circuit tester is 48-1000V (low sensitivity). Pressing the "S" button switches to 12-1000V (high sensitivity), enabling both standard and low voltage (12-1000V AC/48-1000V AC) for more sensitive and flexible measurements. Furthermore, it is easier to identify live and neutral wires when the wires are close together.
【Non-Contact Tester with LCD Screen】With an NCV inductive probe for AC voltage; simply place the tip near a terminal block, socket, or power cord, which can indicate the live and neutral wire without any safety concerns. When the buzzer sounds slowly, the light flashes slowly, and the LCD screen displays green, it is a neutral wire. When the buzzer sounds rapidly, the light flashes rapidly, and the LCD screen displays red, it is a live wire.
【Fast Break Point Test】This voltage tester pen can function as a perfect break point detector. Use the high-sensitivity mode during testing; it can help you quickly find the fault point and alert you to electrical problems. A handy voltage detector for electricians and homeowners.
【Compact Design with LED Flashlight】The electrical tester comes with a bright LED flashlight, allowing you to work in the dark. It automatically shuts off after 5 minutes of inactivity to ensure longer runtime. A low-power indicator quickly informs you of the battery status. Its compact, pocket-sized design with a pen hook allows you to carry it in your shirt pocket.
