Klein Tools NCVT1PKIT Electrical Tester Kit with Non-Contact Low Voltage Test Pen, 50 to 1000V AC and GFCI Receptacle Tester, 2-Piece

This device is GREAT. Put the two AAA batteries in (came with it). I also watched the video. Used it today as I needed to replace a basic light switch. Came in VERY handy. I also have been watching my dad use his old two-wand test meter from the 1970s. This is SO MUCH EASIER and it works!!!!!! When the line is hot, the red light goes on and you get a warning noise. If the line is cold the device light remains green. Just told my daughter to buy this for my dad for Christmas.

Great little tester. Durable, long lasting battery, easy to use, and works great. Not a cheap unit, and easy to read voltage meter .

I upgraded to the Klein NCVT1P after my generic tester kept giving me ghost readings. This tool is much more precise; it only alerts when I’m actually near a live wire, rather than just in the general area. The 50V to 1000V range is perfect for home DIY, and the bright green LED gives you peace of mind that the batteries are actually working before you start testing.

Power switch on my old sensor from a different brand was the clip sliding back and forth. It never worked right, and you couldn’t tell if it was on or off. This one has a power button and lights up green when it’s on, and flashes red when it detects voltage. Audible alert is loud enough for my deaf ears to hear it. Glad I got this one. It fixes all of my complaints about my previous one.

Came with batteries, thought I got the rechargeable one. Still worsk perfect

Like the title says, I’ve bought 2. Main reason is a temporarily lost the first one. lol they work great and are worth the money.

Excellent for detecting active current. I can work safely. When it detects the current, it emits quality sound and red light. It gives me precision to identify wires. Very easy to use Also to know the errors in the outlets.

Used this to check for a circuit in the wall and I'm clearly still alive. That alone speaks for the accuracy of this tool. But no jokes, Klein Tools are quality. They cost more but they have durable, well-built, accurate and do what they are made to do.

This is a must have for any jacks of all trades like I am. I already had one, but I couldn’t find it so I ordered this. This works perfectly and gives you a great layer of safety when doing electrical. It’s a bit pricey on Amazon, but I needed it quickly and it works as described. Klein tools are good quality.

Muy útil y gran calidad

Produto muito bom. Muito Útil para verificar fios elétricos se estão energizados.

Muy buenas marca muy buen precio excelente calidad medición exacta

Já tive diversos testadores de energia, desde os clássicos ao digital em corpo de termômetro, aos novos testadores sonoros de marcas white label chinesas, este se destacou claramente. Ao ligar emite uma luz verde que indica seu funcionamento, sensibilidade grande sem precisar enfiar sua ponta chata (indicada para tomadas americanas) no orifício de plugs elétricos, ele detecta tensão apenas na superfície. Ele tem uma sensibilidade que varia entre 50 e 1000 Volts e funciona em alguns cabos de carregadores para celular com ainda menos voltagem. Essa sensibilidade é destacada por bips diferenciados como um detector de metal que bipa lentamente para mais distante (voltagens baixas) e mais instigantemente para voltagens mais altas como 220V da minha região. Sua estrutura é mais robusta e melhor construída que as concorrentes, na foto mostra uma das que mencionei. Para uma ferramenta de detecção de energia para se trabalhar em segurança eu dou nota 10. Se você precisa de algo mais especifico do que isso recomendo procurar outro tipo de ferramenta. Recomendo!
