Product Description

The NCVT-3 is a non-contact voltage tester with an integrated flashlight. The voltage sensor detects 12-1, 000V AC and indicates the presence of voltage in cables, cords, circuit breakers, light fixtures, switches, outlets and wires as well as AC voltage in doorbells, thermostats, low voltage lighting and irrigation systems. Includes both visual and audible signals. The NCVT-3 is rugged enough for any job site. Detects voltage-inch range of 12 - 1000 vac. Visual and audible signals indicate the presence of voltage. Detects non-contact voltage-inch cables and switches. Audible voltage indicator beeps at a greater frequency the higher the voltage that is sensed, or the closer to the voltage source. Auto power-off" Conserves and extends battery life. Screw-thread battery cap with O-Ring ensures protection against dust and water ingress. Lightweight, compact tool with pocket clip provides convenient storage and quick access. IP67: dustproof and waterproof. 6.6 feet/ 2 Meter drop protection. Cat IV safety rating for 1000V.

    Being a homeowner DIY’er I thought I knew enough about tools to own most of the essential basic ones. I literally just found out about the existence of this type of device by reading an especially well-written setup guide for a wall switch. For years I’ve used one of those little plug-in polarity/GFI testers when I wire an electrical outlet to make sure it’s right. The same tester also gives me assurance that I didn’t forget to turn the circuit breaker off. But for wall switches and other wiring (especially in an older house that has wiring shortcuts) I’m never 100% sure that there isn’t a hot wire in that box or which one of those two identical black wires is the lead. Finding this tool isn’t just nice, it’s mandatory.As I shopped for the right tester the biggest selling model was a fraction of the price of this one from Klein Tools and I’m sure it would have worked just fine. But working with electricity isn’t the time nor the place to go low budget. I was attracted to this one primarily by the five LED’s that not only show you the presence of voltage but gives you an idea of proximity and strength, that plus it has a warning beeper for good measure. It is a non-contact type, which seems to be what the majority of them are. I wasn’t sure why that was important until I realized that it will work through wiring insulation, cable caps and with those switches where the wire is pushed into a hole in the back of the switch rather than attached to an exposed terminal. It makes a lot of sense you need a tester that doesn’t actually have to touch a bare wire to warn you of the presence of voltage.This model includes a built-in LED flashlight, partially contributing to its higher cost. The very last thing I need in my house is another flashlight and that almost turned me off to paying extra for it. Then I got to thinking about those real-life scenarios in which I’m working deep inside a terminal box and guess what, I had to turn the circuit breaker off which means none of the room lights around me work. Of course I need a flashlight and I only have two hands, so having the flashlight built into the end of the same tool I’m using to check for voltage isn’t just a convenience, it’s an important design feature.I’ve never owned anything from Klein Tools but I’ve always heard that they are one of the best brands. Did you know they were founded in 1857? That’s 22 years before Edison invented the light bulb.I'm surprise and disappointed that a company with such a highly regarded reputation is so lacking in a how-to-use owner’s manual. They show an illustration of the switch locations and how to replace the batteries but that's about it. I guess they assume someone buying this knows all about using it but they're wrong. They need to include a detailed tutorial on the proper use of what to do and what not to do in typical DYI use of a non-contact voltage detector.The tester, which combines the best features of the Klein NCVT-1 and NCVT-2 and adds more is surprisingly rugged feeling, it may be the first one I’ve owned but I’ve got a feeling it’s going to be the last one as well.

    5.0 out of 5 stars Useful and reliable non-contact sensor, great design
    Reviewed in the United States on August 14, 2023
    First, I am not an electrician -- so I don't use this every day. But mine has seen regular use on 120 and 240V wiring, and earned its place in my electrical hip pouch. The non-contact tester has been sensitive and reliable, and that is the key function. Higher voltages light more LEDs, and there is a blue LED to indicate power/sensing on. Like all NCVT devices, make sure to check it on a known live wire before each use -- and check the instructions. The built in flashlight is good enough for close up work (see the pic) but I carry brighter flashlight too. Battery life has been very good -- still on the original set after about a year. It has survived a couple of drops onto concrete, and getting seriously wet once. If mine dies, I will order a new one ASAP. Thanks for reading the review, and I hope it was helpful.
