3 Pieces Voltage Meter Tester AC 12-1000V Non Contact Voltage Detector Buzzer Alarm Electrical Testing Led Flashlight Wire Tester Electrical Tool Battery Powered Tester Pen for Live Null Wire Judgment
High efficiency: the wire tester electrical tool(Batteries are not included) will send out a variety of alarms through sound and light, when a voltage is detected, the tip will light up and beep, which is easy to judge, saving time and energy.
The voltage pen tester uses a non-contact method to detect voltage, so you don't worry about the possibility of electric shock.
Sensitivity adjustment: this non contact voltage meter has 3 levels of sensitivity to choose from, the default is to enter the low level (buzzer beeps-once), press the [S] key to enter the middle range (the buzzer beeps twice), and press it again to enter the high level (The buzzer beeps three times), press again to return to the low gear (the buzzer beeps once.
Automatic shutdown function: when the ac voltage detector is not operated for about 5 minutes and no voltage signal is detected, the tester will automatically shut down.
The volt tester pen can be widely applied in circuit breakers, lighting devices, switches, sockets, wires and anywhere needed.
Low voltage indication: when the battery voltage is 2.6 V, the power indicator flashes 3 times, the buzzer will automatically shut down, please replace the battery in time.
You will get 3 electric current testers in the package, enoug....
Non-Contact Voltage Tester/ Voltage Tester with Dual Range AC 12V-1000V/48V-1000V, Live/Null Wire Tester, ENGiNDOT Electrical Tester with LCD Display & Buzzer Alarm, Wire Breakpoint Finder-VT02(Black)
【DUAL RANGE】The circuit tester accurately detects standard and low voltage (12-1000V AC / 48-1000V AC), which is more sensitive and flexible. Low sensitivity can probe power supply lines such as power boards, desk lamps, computers, etc., and high sensitivity can detect buried walls and other internal wiring detection (depth≤1.18 inches). The electronic pen can beep from low, medium, and high frequency to indicate voltage..
【SAFETY FIRST】The live wire detector detects voltage in a non-contact way, and insulation operation can ensure the safety of testers. Safety Compliance: CAT.III 1000V CAT.IV 600V.
【MULTIFUNCTION, EASY TO USE】The LED flashlight with high brightness can illuminate your workspace in the dark. In addition, the sound, light, and screen display triple alarms, and the voltmeter buzzer alarms loudly, allowing you to feel the voltage visually and audibly..
【High Efficiency】As long as voltage is detected, the Led in the tester pen will shine..
【COMPACT DESIGN】 The electrical tester uses 2 * 1.5 V AAA batteries (included), which will automatically Power Off in 3 minutes without operation to save energy. What's more, the small-sized body and portable pencil pen hook allow you to carry the item in your pocket..
