Things to Consider Before Purchasing Non-Contact Voltage Testers

Before you shop for a non-contact voltage tester, you should examine the following important factors. I’ve included the key components that go into creating a top-notch voltage tester. Make careful to record them appropriately.

Voltage Range Detection

It is advisable that the voltage detector you choose has the ability to rapidly switch between two different detection modes: low voltage AC (12 v to 48 v) and high voltage alternating current (48 V to 1000 V). It is for this reason that I advise you to purchase a dual-range tester so that you may utilize the device in a variety of ways.


One other thing that you need to pay close attention to. The non-contact voltage detector you purchase needs to be categorized within safety organizations’ official measurement categories, namely CAT I through CAT IV, the latter of which is thought to be the highest safety tool classification.

Additionally, observe the AC voltage that follows the CAT categorization. The highest voltage rating that the tester can safely verify is indicated by the particular number.

If you’re unsure whether a product’s accreditation is legitimate, you can contact classification organizations using a personal email account.


It is strongly recommended that you get a device with a sensitivity level that you can modify according on your needs. This function keeps you from inadvertently picking up electrical impulses that might influence the outcome of your exam.


A functional outlet tester is one that has several functions, such voltage signal indications, a laser pointer, an LED lamp, and a battery check function. I fervently follow the maxim, “the more features a product has, the more functional it is.” I thus make it my mission to locate the most feature-rich outlet tester possible.


Invest in an ergonomically built voltage tester that takes handling comfort into account if you want a gadget that is simple to use and operate. When used often, a well-designed gadget won’t lead to any kind of hand tiredness.

Size is taken into account as well. It is advisable that you choose a device that is small in size so you can easily bring it with you wherever you go.

A non-contact voltage tester with a hook so you can even put it in your shirt pocket is something else you might want to acquire.

For your reference, we also offer a list of the most popular circuit breaker finders. Additionally, if you’d like, check out our electrical circuit tracer that is the most reasonably priced.

What Kinds of Non-Contact Voltage Testers Are There?

You may anticipate that there are other kinds of non-contact voltage testers (NCVTs) given the variety of goods that fall under this category. You could even think that there are other names for NCVTs on the market, such as non-contact DC voltage detector or non-contact DC voltage tester. But that isn’t the situation here.

Non-contact live wire testers typically come in two varieties: capacitive coupled and inductively coupled voltage sensors. In essence, the methods used by these two distinct voltage sensors to measure current differ. To find out more about the distinctions between the sensors, visit Reddit.

How Can I Tell Whether the Tester Is Working?

If the tester’s led light or bar graph correctly illuminates while it is in close proximity to active electrical outlets, wires, or paths, you may be sure it is working. The sensors of the gadget are appropriately triggered by the presence of a magnetic field, informing you if the wire you are going to contact has voltage energy at the moment.

Are Non-Contact Voltage Testers safe?

Indeed! Using Non Contact testers, or NCVTs, is safe. These are gadgets designed to swiftly ascertain whether cables are carrying electricity without requiring that they be cut open. They are therefore securely shielded from electricity. To choose the best non-contact voltage tester for your needs, you may go through the many brands that Amazon sells.


If you work on wiring projects, one essential equipment you should always have on hand is a non-contact voltage tester. With this kind of voltage tester, you may check the voltage of power without having to cut and splice cables. Actually, this type of tester is triggered by the existence of an electric field alone.
