Are you looking for a non-contact voltage tester?

Voltage testers are essential tools to have on hand when working with electricity. They come in many shapes and sizes, but the best ones will give you both visual and audible feedback when they detect power at your desired range. This will save you time in determining if there really is any power going through those wires or not.

Conversely, a bad voltage tester is a complete waste of time and money.

So to help you separate the good from the junk—we’ve reviewed the Top 6 Non-Contact Voltage Detectors of 2024.

Top 6 Best Non Contact Voltage Tester

Klein Tools Voltage Tester

Discover the Klein Tools Voltage Tester, crafted for ease of use and unmatched reliability. It excels with a CAT IV safety rating, ensuring protection up to 1000 volts. This tool is designed to alert you with both sound and light, allowing a clear understanding of the electrical current’s intensity without direct contact. The standout feature is its LED bar graph, providing immediate visual feedback, so you’re never left guessing in dimly lit environments.

The flashlight on the Voltage Tester Pen can be used at any time, not just when you’re trying to detect voltage.

The model boasts versatile functionality, catering to diverse electrical tasks with its ability to detect both low and standard voltages. Its auto-shutdown feature is a game-changer, ensuring the battery’s longevity by automatically turning off when not in use, saving you the hassle and extra cost of frequent replacements.

If you’re looking for a mix of versatility, high quality and tonnes of extra features – Klein’s Voltage Tester is the right tool for you.

It comes in variants that offer an optional flashlight or laser pointer to make tasks easier, as well as infrared thermometer so it can do more than just test voltage levels!

Fluke Voltage Tester

If you’re okay with spending a little bit extra on your voltage detector, then we recommend going with this non contact voltage tester from Fluke.
In addition to being the most reliable model in its price range, it also comes equipped with new Voltbeat technology that allows for self-testing—meaning if something goes wrong and there is an issue detected by the sensor itself instead of another device like a nearby voltmeter or oscilloscope.

This nifty feature ensures inaccuracy won’t occur as easily while still providing CAT IV protection up 1000 V!

When you want to avoid getting shocked from a live current, this pen will help. This model works quickly and reliably with its two warning mechanisms that tell the user when voltage is present: by emitting an ear-piercing beep, or glowing red for visual indication of high voltage at work.

Thanks to its durable housing and sleek design, it can easily go on busy jobsites without being damaged as well!

The Fluke Non-Contact Voltage Tester is one of the most durable models on our market. Though it comes with a slightly higher price tag, we think this product pays for itself in its resilience and long-term reliability!

If you love all things Fluke – especially their excellent multimeters – then this voltage pen will be your new favorite tool.

Sperry Voltage Tester

Experience the Sperry Instruments Voltage Tester, a compact, durable, and intuitive device capable of identifying AC voltages ranging from 12V to 1000V. Its adjustable sensitivity dial enhances its precision, especially for lower voltages, ensuring you’re alerted with both visual flashes and clear audible beeps, offering a 360-degree detection experience.

The voltage sensor has some great safety features! The fully insulated probe tip eliminates the risk of contacting live electrical wires. A patented battery check feature ensures that the tester and batteries are operating properly, which can eliminate false-negative readings

Here’s a list of features of Sperry Instrument’s Voltage Sensor:

• Adjustable non-contact sensitivity detects voltage from 12-1000V AC
• Audible and 360-degree flashing visual indication
• Allows for sensitivity adjustments in multiple-wire applications
• Operates from single AAA battery
• Patented battery self-test feature
• Soft grip with a contoured design
• Pocket clip
• CAT III 1000 V Safety Rated

The Sperry voltage sensor is a great buy for anyone on a budget. Not only does it offer all the features you might ask from an investment like this, but with its low price tag there’s no reason not to go ahead and purchase one!

Greenlee Voltage Tester

Greenlee’s commercial electric voltage tester is another one of our favorite products thanks to its expanded versatility when compared to other models in the same price range.

This model features a silent mode that you can use when quiet is needed on the workplace, and also has an automatic shutdown feature which will help conserve battery life for those who are always forgetting their charger at home!

We love this product because it includes helpful design elements such as audible and visual cues if there’s any electricity present- even without output tone of voice or anything else extra like a sounder alarm.

The best part? You don’t have to worry about constantly finding new batteries with these too – just charge up once every few months!

This voltage detector is perfect for those long hours on the job as it’s ultrasonically welded and durable. The battery cover, unlike other models that may require your nails to remove, can come off easily with a little push or pull of one hand!

Milwaukee Voltage Tester

This voltage tester pen is perfect for those who are looking to purchase a reliable and easy-to-use tool. This product, made by Milwaukee, features an ergonomic design that makes it easier than competing models on the market.

As you get closer and closer to the voltage source, the unit starts turning red and emits beeps of increasing frequency until they are so fast as to sound like white noise (learn how a non-contact voltage tester works).

The Milwaukee Voltage Tester is the perfect choice for checking your home’s electrical system. It has a simple design which makes it easy to use and provides quick results with accurate measurements every time!

Southwire Voltage Tester

Southwire’s non-contact voltage tester pen is designed to withstand the elements. If you need a quality product for work sites outdoors, then this IP67 waterproof model will be just what you’re looking for with its resistance to water infiltration and ability to sustain up six-foot drops without any problems!

Southwire also included their patented dual-range detection on this electrical tester that can go from 12V – 1000V or 100 V –1000v so it meets every user’s needs in most cases.
