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 2023.
Buy with the confidence that you’re getting one of the best voltage detector pens available. Let’s dive straight into the reviews.

Top 6 Best Non Contact Voltage Tester
Klein Tools Voltage Tester
- Voltage Tester automatically detects and indicates low voltage (12-48V AC) and standard voltage (48-1000V AC) allowing broad application
- Non-contact detection of standard voltage in cables, cords, circuit breakers, lighting fixtures, switches, outlets and wires
- Non-contact detection of low voltage in security, entertainment, communications, environmental control, and irrigation systems
This voltage tester has an intuitive design that makes it easy to use, and is also extremely reliable. It stands up well against CAT IV safety ratings with a 1000 Volt limit.
Additionally, this non-contact meter emits audio signals as well as visual indicators of your detected electric current so you can know the severity of each reading before going down in for close inspection! The best part? There’s no need to fumble around in the dark – thanks to its LED bar graph on side.
The flashlight on the Voltage Tester Pen can be used at any time, not just when you’re trying to detect voltage.
With a few handy features like an auto-shutdown function that will help preserve battery life if you forget to turn it off and detection for both low voltage and standard voltages, this model is versatile enough for a wide range of jobs!
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!CHECK PRICE
- Safety Rated CAT IV
- Audio and visual display feedback
- Voltage graph
- Includes optional attachments
- Can’t get all extras at once
Fluke Voltage Tester
- Be aware of voltage easily - the tip glows red and a beeper sounds when voltage is detected
- Continuous self-test so you always know it’s working
- Voltage detection range for wide application use - 90 V to 1000 V AC or 200 V to 1000 V AC
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.CHECK PRICE
