Electrical Wiring and installation are the most dangerous jobs in construction and maintenance. One such danger is voltage testing. A voltage tester is one of the handiest tools that an electrician owns.

Electrician apprentices are taught the basics of voltage testing when they are still in school. But for an experienced electrician, it’s essential to be familiar with all kinds of voltage testers.

If you are an electrician, you should know the voltage of the line you are working on and the transients that they deliver. You need to know about this in order to avoid any accidents. This is why we need to use the right voltage testers that deliver quick and accurate results and do not take up a lot of time.

we’ve compiled a collection of the best voltage tester for electricians. The best part is – you can buy these devices for home use too. Read our review below to find the perfect one for your needs.

Buying Guide – How to Choose the Best Voltage Tester for the Money?

When it comes to choosing a voltage tester there are a lot of things that you have to take into consideration. To start with, you’ll need to figure out what type of tester is the best for you. Along with figuring out types of voltage testers, there are also other considerations such as sensitivity level, design, functionality, compatibility, etc. The last step is the price – how much should it cost?

Here are some of the factors you need to consider when shopping for a voltage tester:

Sensitivity Level

The first thing you need to consider is the level of sensitivity of the voltage tester. Some of the most advanced models have adjustable voltage presence detectors that will help you control voltage presence a lot faster. They are reliable simply because the level of their sensitivity is good.

Detectors that allow for dual voltage ranges are able to test voltage presence a lot faster and more effectively than most other detectors.

The good news is – you don’t need to worry about the type of device you end up purchasing. Why? Most of the voltage testers now come with self-testing technology so it’s hard to go wrong when choosing what you think best fits your needs.


Currently, there are 3 different types of voltage tester designs available on the market:

  • Pen Testers: Pen testers usually come in a shape of a marker. To operate these devices, you just need to touch the wire in question. Alternatively, you can run it inside an outlet to check for voltage.
  • Outlet Testers: Outlet testers are about the size of an electrical plug and work by inserting straight into an electrical outlet to perform their functions. They can check for voltage and, in most cases, helps to ensure that the outlet is properly wired. However, they are unable to test circuits that are not connected to an outlet.
  • Multimeters: Multimeters are best in class in terms of versatility and functionality, though they are considerably larger in size than outlet testers or pocket testers. Ideally, multimeters with voltage testing capabilities boast grooves or hooks that are designed to surround a wire for the purpose of detecting voltage, as well as leads that are equipped with points used for testing contacts like outlets and terminals.

Depending on your requirement, you can choose from any of these three voltage tester designs.


The majority of the time, voltage testers are only suitable for checking for alternating current, such as the power that runs through a home or a commercial structure. They are ineffective when it comes to detecting direct current in a car.

However, this does not imply that all voltage testers are one-trick ponies with limited capabilities. In certain cases, pen testers include built-in capabilities such as flashlights, measuring lasers, and infrared thermometers, among other things.

Outlet testers usually give you a warning if the wiring in the outlet is in the wrong direction. Multimeters are capable of measuring AC and DC voltage, as well as resistance, amperage, and other parameters.

The functions that are required in a voltage tester will depend on the specific requirements of each user. Using a pen tester, you can quickly check the power of a wire without having to worry about complicated buttons or switches. However, when working on a range of electrical jobs, a multimeter may prove to be a valuable tool.
