Amprobe Non-Contact Voltage Detector VP-440 - Detect Voltage with No Contact (2734332)

Michael Meyer: As a master electrician, the Amprobe brand non contact voltage detector has been my go to for over 25 years. It still does what it’s meant to do.

DEfo: Had quite a few of non-contact testers since 15 years in the trade, and that's my 2nd one. Battery last like 2 years even tho it's always on, doesn't give a false positive and no false negative if you don't try to test thru thick armor. Only downside, and I don't care, there is no sound for when you're alone and want to use it as a breaker finder.

mike parks: This works as it is supposed to. I like that doesn't have any buttons. It just works. The only downfall, be aware that the batteries must be replaced yearly, or else they will corrode, and render this tester useless.

Yooper: Amprobe is a trusted name in the industry and has been around for many years. I carried one of these in my shirt pocket as an industrial electrician. Its not necessarily a troubleshooting tool as much as its a safety tool to let you know voltage is present. The best thing is it's always on, no buttons, no auto off as compared to some other manufactures. You can simply rub it on your shirt sleeve to check if the battery is good, it will light up and the battery life is excellent. Its rated to 1kV so safe to use on 480V circuits. It's also not overly sensitive if you check a wire in a J box.

Frank P.: Just what I wanted. Pricier than many detectors with gimmicky bells, whistles and adjustments. Does exactly what I need it to do, reliably, no more, no less. Almost identical to my original FLUKE which I had gotten used to but seems to have been discontinued.

Works great.

electron: This is a great NCV detector. I have it with my Amprobe CT 100 kit (circuit tracer). Simple and easy to use for the professional and the home owner. Great care and proper safety need to be exercised when using these types of tools and is by no means a replacement for a good volt meter or a "wiggy" style tester. A "live, dead, live" test should be done prior to working on any possible energized circuit. That being said, if unsure, call a professional. Reliable and easy to use and no frills. Lights up in the presence of circuit voltage listed in the specs. I have also used mine and have obtained a positive live light on a 50 V circuit but I wouldn't rely on it for anything lower. I tend to protect these types of tools from being banged around or dropped too much. They could be considered precision and if dropped or abused they will fail. I trust mine only after a "live, dead, live" test every time I use it. Battery life is good but I change mine every 6 mos. Trusted name in Amprobe gives me confidence in the product. Being a licensed electrician I would recommend it.

B. ClarkB. Clark: I have electrical projects coming up, where I need to cut into an existing circuit. I can turn off the circuit breaker, but in the attic, there's no way to know for sure if the power is off on the cable I need to cut. My search for a reliable non-contact voltage detector brought me here.

I must have looked over all the different brands here on Amazon. Many reviewers, unhappy with their present purchase, referred to the Amprobe brand as what they went to, or were going to buy. This was what made me decide to buy this specific non-contact voltage probe.

► CAUTION - Always test this device before using it, to ensure it's 100% functional!

The Pros:
+ The shipping is free.
+ Comes with 2 AAA alkaline batteries installed.
+ Nothing to turn on, since it's always on.
+ Very sensitive, even detecting which side of the cable is HOT!

The Cons:
- Not the lowest cost non-contact voltage probe, but sometimes it's better to pay more for quality.
- No audible, just a red flashing light when a voltage is detected. Having an audible wasn't important to me, but some may want an audible with the light.
- As with most non-contact voltage probes, this...
