Best Voltage Detector

You might be Do-It-Yourselfer or perhaps your profession requires you to handle pieces of electrical equipment, then you should definitely have a voltage detector as part of your toolbox. This handy tool will usually have the design of a large pen, and it’s primarily used to determine if there’s an electrical current present in the item or wire you’re testing. There are non-contact models that help you ensure that you don’t have to touch the wire when looking at its voltage readings. Read on to get to know more of our guide that’ll help you get the best voltage detector.

Klein Tools NCVT-2 Voltage Tester

Klein Tools NCVT-2 Dual Range Non-Contact Voltage Tester

When using the Klein Tools NCVT-2 Voltage Tester, it’ll automatically detect and indicates any low voltage and standard voltage readings. Therefore, there’s a broad range of applications for this voltage detector. It’s a non-contact variant which means you don’t have to touch the wires if you want to get a reading. It’s useful for checking the standard voltage in cables, circuit breakers, switches, outlets, wires, and lighting fixtures.

Sperry Instruments GFI6302 GFCI Outlet / Receptacle Tester

Many individuals in the DIY and electric industry know of the Sperry Instruments brand, and the GFI6302 GFCI Outlet / Receptacle Tester is a great tool to add to your toolbox. It’s highly durable and high impact resistant construction makes it ideal to work with for heavy-duty uses. Combine it with its ergonomic design, and you’ve got a voltage detector that you wouldn’t mind using a lot.

Fluke 1AC-A1-II VoltAlert Voltage Tester

The Fluke 1AC-A1-II VoltAlert Voltage Tester help you test wires, cables, and objects to know if it’s properly working. When it detects any electrical current, the tip will glow and it’ll also make a beeping sound. Once it does, it’ll let users know any indication of the presence of voltage.

What to Look For?

While there are many different variations of voltage detectors on the market, you should only buy what you need. After all, you don’t need a toolbox filled with only voltage detectors, now do you? You can start your search by looking at the features of the unit. For instance, some testers can measure both high and standard voltage currents. There are even some models that’ll allow you to tell the difference between the two readings automatically so you don’t have to shuffle through menus or buttons just to get to know what the numbers mean.

You might even want to look for a voltage detector that comes with a bright LED flashlight. Why? Think about this scenario – you’re trying to look for a particular tool inside your den or garage but it’s too heavy to pick up, or perhaps the wires are located on the wall. Now, when you approach the room, you find out that the light suddenly decided to die out. So instead of giving up or using a flashlight in your free hand, you can just use a voltage detector with a built-in flashlight instead. It’s akin to killing two birds with one stone.

Aside from having bright LED flashlight feature, the voltage detector should also have a bright LED indicator. The use of this functionality is highly practical as it’ll allow users to know if there’s a current present on the device or wire. Some voltage detectors will even flash different-colored lights depending on what range of voltage you’re currently dealing with.


When looking for the best voltage detector, the primary factor that you should be looking into is its accuracy. You never want a voltage detecting tool that’ll display random numbers because it would otherwise defeat the whole purpose of having and using such a device.
