Dual Range, Non-Contact Voltage Tester

Works great! Got one for safety and it has already saved me! They are not expensive, just get one.

I bought this to test for bad leds on outside light strings. On the 12 volt setting, it works like a charm. Also handy for testing doorbell circuits or low voltage outside lighting. Of course the 120 volt setting is great for house wiring Issues and to see if a circuit is live or not. This was exactly what I would expect from a Klein tool. Works just like I hoped it would.

Fast delivery and exactly what I was looking for.

I've used many NVCTs, but this one is my choice to bring to work. Reliable. Illuminates so that you know it's powered on. Lights up red and produces an audible beeping when voltage is detected. Very accurate...it can distinguish between multiple wires that are close together. As far as these testers go, this one is my first choice. When I work around potentially energized circuits, I always keep this tool in my pocket. I'm a full-time licensed electrician.

This Klein Tools NCVT2P Dual Range Non-Contact Voltage Tester is one of those simple tools you do not realize you need until you start doing electrical work around the house. Whether checking outlets, light switches, ceiling fixtures, extension cords, or breaker lines, it gives quick peace of mind before touching any wire. What makes this model better than cheaper testers is the dual voltage range. It can detect both low voltage and standard household AC voltage from 12 to 1000V, which makes it useful for more than just outlets. Great for thermostats, doorbells, irrigation wiring, and regular home circuits as well. Klein lists both visual red light alerts and audible beeps, plus CAT IV 1000V protection, auto shutoff, and dust/water resistance, so it feels like a professional-grade tester rather than a disposable gadget. It is very lightweight and pen-sized, so it clips easily in a pocket or tool bag. The bright indicator lights are easy to see, and the beep is loud enough to hear even in a noisy work area. Response time is fast — just place the tip near a wire or outlet and it immediately lets you know if power is present. Another thing I like is that it feels solid in hand. The battery cap seals tightly, the body is durable, and Klein built it with drop protection for jobsite use. Many electricians online mention these testers are excellent for quick safety checks, but still remind users that non-contact pens should be used as a first-line indicator and not the only verification before major electrical work, which is good advice. Pros: -Dual range detects low and standard AC voltage -Loud audible alarm and bright visual indicator -Compact and easy to carry -Durable Klein build quality -Auto power off saves battery -Great for homeowners, DIY, and pros Only downside is that, like all non-contact testers, it can occasionally give a false positive around bundled wires, so it is best used as a quick safety check rather than a replacement for a full multimeter. Overall, this is an inexpensive but extremely valuable electrical safety tool that belongs in every toolbox.

I am careful with electricity... this is not the primary way I check for safe circuits. I use this as a secondary check to make sure I am not missing something (like two breakers powering a single box). It works well, and gives me confidence that I didn't overlook something. My only complaint is that the "power-off" beep is the same as the beep for when a hopt wire is detected. Invariably, I will confirm that a box is safe using this tool. and toss it in my toolbox. As I am working on the wires, I will hear the tool do a power-down beep, and my heart will skip a beat thinking that somehow something is "hot". Other than that, it's a great little tool, and I have two so I am never without one.

it works. tried it in a 120 V ac outlet. no idea about anything else. home fix it person

Neat little gage that will keep you from being shocked or hurt.

Handig stukje gereedschap. Geschikt voor iedereen die met spanning werkt.

Works very well. I want to give it 4* because it is costly however it works so well and is very handy that I still have to give it 5*.

Excellent

Klein Tools are an American Brand akin to Fluke in the UK - A good start. Amazon sold and despatched - Best and most reliable way of buying from Amazon - Another plus point IMO. Not the cheapest as so many Chinese copies out there at half the price but, again IMHO this is WELL WORTH the extra. It arrived next day via Prime (in basic Amazon packaging but very sturdy moulded plastic covering from the manufacturer). It works really well, good level of sensitivity differentiating easily where cables are close together. Worked straight out of the 'box' having inserted the AAA batteries and hasn't missed a beat so far. It has an auto switch off to conserve the batteries which is so useful. My previous Maplin tester had a small torch built into the end which was actually useless and, as I don't work in the dark, hardly something I miss. So far definately so good. It also seems pretty robust and Klein even claim it should survive a a drop of a couple of metres. All in all, a nice usefull piece of kit at a fair price. Edit: Don't know what Amazon have done to the picture resolution, the instruction sheet which gave detailed info of it's capabilities had a resolution of 4677 x 3307 when I posted it - ah well !

Working exactly as expected, reading the manual is important as there is only one button for several options.
