Features

  • 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 and the percentage value will be larger. At the same time, the screen will be red or green, red means high voltage and live wire are detected, green means low voltage and null wire are detected
  • NON-CONTACT: With NCV inductive probe for AC voltage; Just place the 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 Test. Handy circuit tester for electricians, homeowners
  • DUAL RANGE: Detects standard and low 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, and the percentage value can display the voltage signal intensity more intuitively
  • SECURITY LEVEL: IEC rated CAT III 1000V CAT IV 600V, Meets CE requirements; The electrical tester is safely double insulated. High Voltage Alert to warn you of voltage above 90V, the screen turn red and the safety symbol on the screen shines

  • Highly recommend
Color: Black Size: HT100s
This voltage tester works exactly as expected. It is very easy to use and the non-contact feature gives me peace of mind when working around outlets. The sensitivity is great and it feels like a very safe, accurate tool to have around the house. Highly recommend!

This is a great voltage reader. Safe, accurate readability. Love the built in flashlight. Great price and fast delivery! Must have in your tool bag!

  • Exactly what you are looking for
Color: Red Size: HT100s
Saved my butt, and it works really well. Why it saved my butt? I changed two smoke/CO detectors without this and it went well. Decided for the following six I planned on changing that I should get this device. Sure enough, halfway through while using it one of the black cords was live even though the light next to it turned off when I flipped the breaker. Went back and flipped a few more and the reading was at zero. Game changer! Additionally, it’s easy to use, has a useful light, and can clip on your belt loop. ... show more

  • Works great!
Color: Red Size: HT100s
Genuinely impressed by this tester's dual-range sensitivity (12V and 70V–1000V) — catches both low and high voltage without swapping tools. The LCD signal percentage display is a standout feature, giving real confidence about wire liveness rather than just a yes/no beep. Breakpoint finder works surprisingly well for tracing hidden wiring faults. Build quality feels sturdy, the buzzer is loud and clear, and the one-hand operation is intuitive. A must-have for home electrical work. Great value for the price. ... show more

  • Every DIY'er Should Have This In Their Toolbox
Color: Black Size: HT100s
Works perfectly as intended and described. Excellent value and a very good tool to have around for DIY homeowners. Instructions are a little hard to decipher at first, but are accurate and comprehensive.

  • Easy to use & great for DIY
Color: Red Size: HT100s
I used this to help change out a light switch in my home. It was my first time ever touching wiring in my home, I was very nervous but with this product I was reassured it was safe before working. If it detects voltage it beeps loudly and a red light flashes. It also gives you a percentage reading on the screen. I would recommend this product. ... show more

Great little device that lights up and sounds an alarm as you get close to the hot wire. Easy to use.

  • Great to use for replacing outlets and switches
Color: Red Size: HT100s
I got this detector to use when replacing all the outlets and switches in our house. This was a necessity to ensure my safety while doing that. It was accurate and helpful! Just make sure you don’t test wires that are too close together because it could pick up voltage on a nearby wire and mislead you to incorrectly identify a hot wire (that is more of a user error rather than an issue with this product). ... show more
