Buyer’s Guide For Best Non Contact Voltage Tester

Before buying any voltage detector pen, there are factors you should consider. Here are the main factors you need to look at to get the best tester;

  • Safety Level

Ideally, you consider your safety while using these testers since you’ll be working on live electric currents that can electrocute you. In equipment, the safety level is rated according to the category level.

Either your device has a CAT I, II, or IV rating, which is the safest level. However, if you want to buy a voltage detector pen, don’t settle for a safety level less than CAT III.

Apart from the CAT category, it would help to consider the maximum voltage of the device you’re to use. The non-contact voltage detector have maximum voltage ranging between 600v and 1000v. You’ll be safe with this as it will also protect you against overvoltages.

  • The Design

You should also check the design of the equipment to have an easy time handling or carrying it around. You should in this line consider its size as you’ll not love carrying a bigger tool nor a weighty device. If you can, go for the ones with clips that can easily fit your pockets.

  • Sensitivity

It’s advisable to go for a device whose sensitivity is adjustable to meet your requirements. Doing this will reduce the chances of having false positives and ensure the voltage you’re monitoring.

  • Price

Some testers give value for your money, while others don’t. To avoid spending much, work within your budget but don’t forget to check the features you’re looking for in the device.

  • Brand

Although popular brands are expensive, it’s advisable to go for them, especially when working on electricity. Remember, electric currents can electrocute you, something that’s not safe at all. But with the famous brands, you’re sure of adherence to production standards.

  • Voltage Range Detection

Don’t forget to check on the range of detection of the device you’re about to buy. You can either go for a high voltage detection device that works on switches or low voltage or AC suitable for doorbells.

But if you can afford the dual-range voltage detection tester, the better. Some of the devices also switch the ranges automatically, giving you an easy time.

  • Voltage Display

Another thing you should also consider in a tester is the voltage display. Having the best tester that can’t allow you to see the readings is not worth it. Most of these devices have an LED display at the tip. If you place the device near the electromagnetic field, the LED will light up.

These testers can also show the presence of voltage through buzzing sounds. If you can, go for the one with both audible and illuminating alarms so that you reduce your chances of misinterpreting the results.

  • Functionality

Before you settle for a tester, check if it can perform other functions too. For example, apart from your tester pin showing you the current level, you can use it as a torch. Others also act as thermometers which reduce the costs of purchasing additional tools.


Can a non contact voltage tester work on direct current?

No. These devices can’t do this. They only detect electromagnetic field that comes from AC. Direct Current (DC) can’t create a similar electromagnetic field, making them unsuitable for DC work.

What’s the difference between voltage tester and multimeter?

Voltage testers detect whether there’s voltage or not, while multimeters measure how much voltage is in a circuit. Also, a voltage tester doesn’t need to touch the wires and terminals to work. But multimeters have to be in contact with the wires by connecting the probes with the circuit.

Multimeters can also perform several tasks like testing resistance, voltage, or voltage, which voltage testers can’t.

Are you safe using the voltage tester?

You’ll be safe using these devices. First, however, you’ve got to get a quality device that’s well insulated with no visible metal or conductor. Also, whenever you notice any default, get a newer one that won’t put your life at risk.

How will I know if the tester is functional?

The first thing you’ll notice is the light on the LED display if this device comes near an electric current. This is because the magnetic field activates its sensors, allowing you to identify if the wire you’ve got has voltage.


There are different brands of best non contact voltage testers, each with its benefits and disadvantages. However, for you to settle for the best tester though, you’ve got to consider several factors apart from the brand.

Look at its functionality, price, or size. You should also check on its sensitivity features and its dual-range voltage detection beforehand to get accurate results. In our review, you can go for Klein Tools NCTT-2, which has a double detection range and can perform on low or high voltages.

It also switches the ranges automatically, allowing you to work with ease. Non-contact tester device is ideal for both a professional or a DIYer who wants to fix minor electric faults around the home.

If you’re a professional, you’ll require a device that delivers up to your expectations and ease. It would help if you also looked for a durable tool that won’t break each time eating your money. Accuracy for a professional is also key to check for a tester that will not disappoint you.

Don’t limit your device to a specific sensitivity or range so that you can work anywhere anytime without changing the device. But pricing is also essential as you need value for your money. So don’t spend too much on a device that performs or meets your standards.

I hope this guide will help you choose the best voltage tester that you’ll live to cherish. The 15 are the best in the market and will allow you to work without compromising your safety as they work without coming into contact with the wires.
