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, don’t settle for a safety level less than CAT III if you want to buy a voltage detector pen.

Apart from the CAT category, it would help to consider the maximum voltage of the device you use. The non-contact voltage detector has a 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 or a weighty device. If you can, go for the ones with clips that can easily fit your pockets.


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


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.


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 famous brands, you’re sure of adherence to production standards.

Voltage Range Detection

Don’t forget to check on the detection range of the device you’re about to buy. You can either go for a high voltage detection device that works on switches, 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. The LED will light up if you place the device near the electromagnetic field.

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.


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 a voltage tester and a 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.

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 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.

Final Thoughts

Look at its functionality, price, or size. You should also check on its sensitivity features and 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. A non-contact tester device is ideal for both a professional and 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.
