Will the 1LAC-A-II detect 120VAC? The Product Description says it "detects 20 to 90VAC, but also says "Applications include testing...an outlet"

My husband is the one who bought the 1LAC-A-II for his work, and he says it does detects from 120VAC to 277VAC.

How do I know this is the real thing?

It is the real thing, I've used it multiple times and I am very satisfied. (as an aside)I was watching 'This Old House' and saw the electrician on the show use the Fluke to check his circuits.

Will this detect voltage in water?

This tester has a minimum voltage of 90v. It is not waterproof. For that situation, you're going to need a good voltmeter.

Does the fluke 1lac-a-ii low voltage detector beep when voltage is detected?

Owe yes strong beep you can hear, It also beeps when you turn it off but not when you turn it on the white part lights up flashes and beeps when you detect voltage

Much better than my Milwaukee voltage detector.

This voltage detector works much better than my Milwaukee one. That’s on me. I read the reviews before I bought the Milwaukee one but decided for my purposes it would be fine. Turns out I was wrong. I don’t even think there was a significant difference in price. I’ve been so happy with my Dewalt to Milwaukee tool changeover and all my Milwaukee tools have exceeded my expectations to the point that I figured it would HAVE to be decent. Plus I know that a good deal of bad reviews are from people who don’t know what they’re doing. However, in this case they were right. The Milwaukee one does not live up to expectations. I am not an electrician, but I do low voltage electrical work in industrial automation applications. Low voltage being 24vdc. I truly do not care whether 24vdc applications are hot or not. However, in the same cabinet there may also be 440+ vac, which I do very much care about. I assess each job individually and find and mitigate risks as necessary and the Milwaukee voltage detector has failed me both by embarrassing me AND by placing me in harm’s way. I had to break out my meter which negated the whole purpose for carrying a voltage detector. I immediately tested this Fluke voltage detector when I received it and am MUCH happier with it, just/ even on residential outlets you can clearly see the difference.

Another fluke winner

Just the 2AC but with higher sensitivity. Does its job well as you’d expect from Fluke.

For low voltage voltage testing

Works great for low voltage detection but I needed one for120volts to 1000 volts so I ordered a different one (VoltAlert1AC-A II) and I like them both but the low voltage one is too sensitive for most of my jobs but I use it on network because it let’s me know when the line or circuits are hot

It’s a fluke

I’m In the hvac field. It’s Definitely on the SUPER sensitive but it’s worth it.

GREAT TOOL FOR ELECTRICAL WORK ESPECIALLY ON OLDER HOMES

I'm restoring an older home and some of the wires aren't color code wired so I wasn't about to guess which was the 'hot' one. This tool is great it helped me install new light switches and electrical outlets plus one overhead light I couldn't get connected right. A must for any handyman who would dabble in electrical work. Small enough to fit in shirt pocket, long battery life, light to tell you which wire is hot and long battery life.

Beeps at everything,

Scenario: 2 outlets — separate breakers. One breaker off. One breaker on. Since this thing beeps from 2 feet away, I have no idea which outlet is on.

Perfect for low voltage

I'm a irrigation contractor where systems are 24-26 volts and this low voltage tester is a must have!

Quality Fluke equipment

Works really well but stupid me ordered the wrong model. This one is low voltage 20 to 90VAC. I'm still glad I have this test instrument though. Fluke is the best, no question.
