Klein Tools NCVT 2, Automatically detects and indicates low voltage

Non-contact detection of standard voltage in cables, cords, circuit breakers, lighting fixtures

Klein Toosl, ncvt-2

Klein Tools, Klein ncvt2

Provides non-contact detection of AC voltage.

Detects 12 to 1000V AC with simultaneous visual and audible voltage indicators.

Bright flashlight illuminates work area and may be used independent of voltage detection function.

Visual LED bar graph indicates the presence of voltage - the higher the voltage sensed, or the closer to the voltage source, the more LEDs light up.

Customers are dissatisfied with the beeps of the tool. They mention that it often beeping when they are 2 feet or further from any electric. They also say that it makes all kinds of beepping sounds.

"...The darn kept beeping when I put the tester to my bathrom light...." Read more

"...In high voltage mode, it only beeps at high voltage. Understanding that makes using the tester much easier." Read more

Not as skookum as i hoped.
4 Stars
Not as skookum as i hoped.
I purchased this Non-contact voltage detector because its made by Klein tools a reputable tool company. Before i purchased this one i bought another generic brand version of this tool. it worked surprisingly well. How ever eventually it broke. I was considering replacing it with the Klein Tools NCVT-3 how ever the high tier detectors by klein lack the protruded tip that allows you to suspend the detector in a outlet. A feature i find useful when im trying to find a breaker or switch for an outlet. So i went with this version.It is very handy. It is smaller and feel lighter than my generic version. Its bright color makes it easy to spot. It is UL listed and very simple to use. it has no weird bumps or ridges. its a little wider where the plastics are joined and tapers into its irregular symmetrical hexagonal shape. You can hardly feel lines from the molds meet.Its design is smart. One flat PCB board that slides in through the rear. One clear plastic piece and a cap. Theres some padding to stop the batteries from clinking inside. With a spring on both the negative and positive terminal. meaning you can shake the thing and it wont raddle.My old one failed when the plastic on the the tip snapped exposing the metal tip. Klein knew this was a weak point and they beefed up the plastic. The plastic on the tip is thicker. Leading up to the tip its much more rounded meaning its better able to distribute pressure. I did purchase a small case to house the tool in while in my tool bag just in case.There are few things things i DON'T like about this tester.I dont like the red cap. Its is very thin and it wasn't cleaned up. If you look carefully at the pictures i provided (And the 3rd photo on the listing) you can see the yellow plastic from behind the red cap. The plastic is very very thin here. On mine its clear they didn't properly clean the edge from the plastic as well.I don't like the use of complaint mechanism. In this case the use of the clip to hold the red cap on. The plastic will get fatigue and it will get brittle. When that happens it will break and this tool will become trash.Last is the is the button. It feels sloppy. The issue is the lack of touch feed back. Maybe this wasn't an issue a few years ago. But now especially now that we are used to haptic and audio feed back. Think of your phone. As you type on it your phone may vibrate slightly on each touch or play a small tick tone as you press the screen. When you press the button on your tv remote you know the button has been pressed when you feel the rubber dome collapse.This tester doesn't have any feed back. its possible to press the button light enough that you feel the dome buckle and bottom out yet the tool didn't receive and input. And when you do press it hard enough to turn it on the light doesn't come on immediately. it makes the tool feel a little bit unresponsive. klein tools if your reading this is an easy fix.I will say that i work side by side with a lot of electricians and we talk about tools. A lot of them have had these voltage testers for a very long time with the belt clip intact.Conclusion: This tool is an essential in any tool box hows ever im afraid it wont be a forever tool. And i recommend you purchase a case to carry the tool around. And if you wont be using it to find breakers then id recommend the Klein tool NCVT-3 instead. I suspect the threaded cap will be more durable in the long run then the clip on cap. It also has a nice meter and LED built in.
