3000 Non-Contact Voltage Tester, Always-On AC Voltage Detector 50-1000VAC, CAT IV Certified Electric Tester, Made in USA, No On Off Switch, Audible Visual Alert, Pen Size Electrician Tool

This is my favorite non contact voltage tester out there. It’s small and simple to use, never lets me down. The tester has a perfect sensitivity not too much or too less. I’ve bought many of these. Usually I either lose them or run them through the washing machine, otherwise they seem to last forever. I also love that there is no power on and off button, just check and go

Everyone knows how frustrating NCVT’s can be. The cheap ones work, but not reliably, & sometimes stop working. I took a few NFPA courses, and the electrical instructor recommended the Santronics 3115 tester, as it’s the only one approved by OSHA. I got one, and it’s great. But an audio NCVT is also useful & Santronics 3000 fits that bill. It’s every bit as accurate & tough as the 3115, and doesn’t have any of the stupid bells & whistles of “fancier” units. Santronics is also the only American company making NCVT’s. I’m a facility maintenance worker at a hospital, so we are frequently testing & repairing electrical devices & circuits. I’d had a couple Klein’s over the years, & an excellent Fluke tester. The Klein’s are good, but seem to have long term reliability issues. My Fluke is actually made by Santronics, but their newer units are not. Fluke’s newer models also require a separate tester for low voltage. Pros: • Always on • Bright Light • Loud Beep • Aside from minor bumps which make it flash, I haven’t had any false positives or negatives. • Polycarbonate construction is really tough • Made in the USA • Great Price Cons: • Unlike the Santronics 3115, which visual only, the 3000 is not OSHA approved. Probably a bureaucratic thing, as the 3115 is the ONLY OSHA approved tester.

No buttons to push. It’s always on. It flashes when it detects voltage close by and beeps when it touches a hot wire. So it works very well in boxes with multiple wires and switches.

My favorite tester. Very low sensitivity. You can drag it across an extension cord and see how the hit wire twists. It’s rugged, reliable, and I can actually use it in a j box to identify which wire is truly hot.

Very useful at separating Hot from neutral, it’s got the right sensitivity level. And the fact that is always on is a game changer.

Santronics is very accurate. My Klein would often signal "hot" when a neutral wire was close to the hot wire. Klein would also signal "hot" when a receptacle was getting very little voltage, and not getting enough voltage to turn on a lamp. This is very confusing. This A/C volt detector doesn't give false positives for 120/240 USA home receptacles. I try not to buy anything made in china but have when I didn't have a choice. I tried this one because it was USA made and it turned out to be a much better product for an armature.

A great electrical tester and functionality

I'm a home inspector and I've used a lot of these type non contact voltage detectors and this is the best brand yet. For what I do the detector shouldn't be too sensitive. A detector which is too sensitive is no use to me. This one is just right. I can touch it to the hot side of an outlet and it beeps but won't on the neutral. It's always on which I like and it beeps and flashes when you touch it to a hot wire. Also it looks sturdy. A good product I'll buy again.

Very handy to have in your pocket to check for live wires. Not a substitute for a meter though obviously.

Fantastic performance. Perfect sensitivity. Love not having to turn on and off.

I have not caused anymore explosions since owning it unlike my last one.

2nd time purchasing this unit. It stopped working after 3 months. Do not buy, absolute garbage
