What to Look for When Buying Non Contact Voltage Testers
I’ve listed some critical factors that you must take into consideration before shopping for a non contact voltage tester. What I’ve outlined are essential aspects that make an excellent voltage tester. Carefully note them accordingly.
Voltage Range Detection
I recommend that the voltage detector you get can quickly switch into two distinct detection modes, namely: high voltage alternating current (along with the range of 48 V to 1000V) and low voltage AC (12v to 48V). The reason why I suggest that you get a tester capable of dual-range testing is so that you can use the device in a plethora of ways.
Yet another component that you must heed carefully. The non contact voltage detector you’ll buy must be sorted into official measurement categories of safety organizations — in particular, from CAT I to CAT IV, with the latter being regarded as the highest safety tool classification.
Moreover, take note of the AC voltage directly after the CAT classification. The specific number outlined states the maximum voltage rating the tester can safely check.
If you’re in doubt, you can send a mail to classification agencies from your personal email address to determine whether a product’s accreditation is genuine.
I highly suggest that you get a device with an adjustable sensitivity setting that you can tweak according to your use. This feature prevents you from accidentally picking-up electric signals that may tamper with your test result.
A functional outlet tester is one that comes with a plethora of features such as a LED flashlight, laser pointer, battery check function, and voltage signal indicators. A rule of thumb that I religiously adhere to is “the more features a product has, the more functional it is.” Thus, I always strive to find an outlet tester that offers the most features.
If you want a device that you can handle and manage easily, then get a voltage tester that’s ergonomically designed with consideration to handling comfort. A well-designed device will not cause any sort of hand fatigue when used extensively.
Size also comes into consideration. I recommend that you buy one that’s designed compactly, so you can portably carry the device around everywhere.
Additionally, you may want to get a non contact voltage tester that comes with a hook so that you can even place it in your shirt pocket.

What are the Different Types of Non Contact Voltage Testers
Given the diversity of products under the non contact voltage tester category, you may expect that there are different types of NCVTs — you may even imagine that there’s a non contact dc voltage detector, non contact dc voltage tester, or just a regular direct current tester in the market. However, that’s not the case here.
Generally, there are two types of non contact live wire testers: an inductively coupled voltage sensor and a capacitive coupled sensor. Basically, these two different voltage sensors vary in how they detect current. Head on to Reddit to learn more about the difference between the sensors.
How Do I Know If the Tester is Functioning
You’ll know that a tester is functioning if the device’s led bar graph or led light properly lights up near a live electrical path, cables or outlets. The presence of a magnetic field aptly triggers the device’s sensors, letting you know if the wire you’re about to touch currently carries voltage energy.
Are Non-Contact Voltage Testers Safe
Yes! NCVTs (Non Contact Voltage Testers) are safe to use. They’re devices specifically made to quickly determine whether a current is running through wires without the need to splice them open. As such, they’re safely insulated from electricity. You can check out some brands of non contact voltage tester Amazon offers to find one that’s right for your use.
Is a Voltage Tester the Same as a Multimeter
No, non contact voltage testers are different from multimeters. In essence, non contact voltage testers can only determine the voltage of electrical devices without requiring you to touch them, hence the name. Meanwhile, multimeters are much more complicated, as they can evaluate and give-off precise readings of AC and DC voltage, electrical capacitance, continuity, frequency, and resistance.
A non contact voltage tester is an important piece of tool that you must have by your side if you’re working on wiring projects. This type of voltage tester allows you to test for electricity voltage without the need to open and splice wires. In fact, just the mere presence of an electric field sets this kind of tester off.
If you want your work to be manageable, productive, and practical, then I recommend that you buy the best non contact voltage tester for your specific use. Trust me, having a reliable piece of tech can save you from heaps of trouble and hassle when working around cables, outlets, and other electric systems.
