  • SAFETY FIRST: When the detected voltage is higher, or the closer it is to the voltage source, it will beep at a higher frequency and the light will be red. Red means high voltage and live wires are detected, yellow means low voltage and neutral wires are detected.
  • NCV INDUCTION: The breakpoint finder has an NCV sense probe for AC voltage, just place the tip near an outlet or power cord. You know voltage is present when the red light turns on and the pen beeps.
  • DUAL RANGE: Detects standard voltages and low voltages (12-1000V AC / 48-1000V AC) for more sensitive and flexible measurements. Press the H/L key to adjust sensitivity to accommodate low ranges for doorbells, thermostats, irrigation wiring, etc.
  • AUTOMATIC SHUTDOWN: The electrical tester is double insulated for safety and complies with CE standards. When the battery voltage is lower than 2.5V, the power indicator will light up; it will automatically shut down after 5 minutes of no operation or no signal detection.
  • COMPACT DESIGN: The voltage tester features a bright LED flashlight for working in dim locations; pocket-sized pen hooks allow you to carry it in your shirt pocket.(Laser: Class 2, maximum laser output <1mW)

  • Non Contact: Just place the NCV tip near a terminal strip, outlet, or supply cord. When the tip glows red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire. Ideal for breakpoint Tests. Handy circuit tester for electricians, and homeowners.
  • Safety First: It will send out multiple alarms through sound and light. When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency. At the same time, the screen will be red or green, red means the high voltage and live wire are detected, and green means the low voltage and null wire are detected.
  • Dual Range: Only detects AC voltage (12-1000V AC / 70-1000V AC) for more sensitive and flexible measurements. Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring, etc; The NCV sensor automatically recognizes the voltage and displays it on the bar graph.
  • Security Level: IEC-rated CAT III 1000V, Meets CE requirements; The electrical tester is safely double-insulated. High Voltage Alert to warn you of voltage above 70V, the screen turn red, and the electric shock warning symbol is displayed on the screen.
  • Compact Size: Bright LED flashlight and backlit for work in dim areas; Auto Power Off after 5 minutes without operation or no signal detection; pen hook allows you to carry it in your shirt pocket.

  • Mains Tester Screwdriver is fitted with a neon indicator in the clear plastic handle which illuminates when the point of the tester is touched on a live voltage source of between 120-250 volts and an earthing contact is made with the metal stud on the top of the handle.
  • Main tester is fully insulated and is supplied complete with full operating instructions and will perform the following tests: continuity, bulbs, fuses, short circuits, cable tracking, mains sockets and microwave oven leakage.
  • Main tester will test electricity up to 250 volts. Hold the Main tester by the insulated handle, do not touch any part of the exposed metal blade. Always test the Main tester before you start by contact with a known live power source. You do not need to touch the touch pad at the top of the Main tester (although it is perfectly safe to do so).
  • The red LED will glow brightly when the Main tester metal blade is in contact with a live circuit, indicating that it is functioning correctly.
  • Hold the index finger against the cap end of the electric pen, thumb and middle finger, and gently pinch the electric pen with your ring finger to keep it stable, and then insert the metal nib into the socket panel hole on the wall or the external power strip socket hole.
