Klein Tools NCVT-2 Dual Range Non-Contact Voltage Tester

We have an older house with equally old wiring. This is a great and safe way to check the reliability of the wiring . Takes just a couple of seconds to check

I got the Klein NCVT2P Dual Range Non-Contact Voltage Tester with my Klein Tradesman Club points on 4/29/26, and it has been a great tool to have. It's simple to use, works exactly as it should, and gives me confidence when checking for voltage. The dual-range feature is especially nice because it makes the tester useful for a variety of situations. I got this as part of the tools I'll be taking with me when I go to the NRVTA in a couple of months. My grandpa and my dad have both trusted Klein Tools for years, and their tools have always held up well, so I decided to stick with a brand that has a strong reputation for quality and reliability. The tester feels well-made, is easy to carry in a pocket or tool bag, and has already become one of the tools I reach for most often. Overall, I'm very happy with it and would definitely recommend it to anyone looking for a dependable non-contact voltage tester.

This is great for the price. It's very durable and dummy proof.

Good Klein tool. Does what it' suppose to.

Good product

[This review was collected as part of a promotion.] I've owned quite a few of these and they are my go to when checking if the power is off. I have yet to have an issue with it reading incorrectly saving me from some bad shocks. Unfortunately I can't say how long they last as I tend to lose mine or a coworker “accidentally” takes it and I never see it again. I can say I've had one for about 2 years with no issues before it was misplaced so it is well worth the price.

[This review was collected as part of a promotion.] I bought this over 6 months ago when I first started working in the industry and have since then used it countless times on the field and in my own home. Having this tool always keeps me aware and safe and It's safe to say it's definitely one of the top tools I own

The method to switch modes is to hold the power button for 3 seconds. The way to turn it on or off is to hold the power button for ~1 second. The issue is that sometimes when you push the button to power off it sometimes doesn't so you're tempted to hold is more firmly i.e. longer but then it just switches modes instead of turning off. Perhaps I'm not used to it yet and I'll get better at it later. #sweepstakes [This review was collected as part of a promotion.]

I utilized this tester to try to detect a break in landscape line. It did not detect current at various places along the line and at the fixture. I had to pull up significant lengths of the cable to find the break, which I then repaired. The voltage of the landscape line coming out of the transformer was 12 volt AC. I would not utilize this tester on landscape line, even though it is rated to detect 12V current. It does not. The tester seems to work fine at higher voltage levels for me, but was not able to detect current at the 12 volt level. The tech specialist for Klein suggested to me that perhaps I was testing DC current, but I was not. It was 12 volt AC.

Hard to work with. Gives high voltage signal on a 5v phone charger cord. Went back to my single signal Fluke. [This review was collected as part of a promotion.]
