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....
