15 Best Non Contact Voltage Testers 2020 [Buying Guide]

Electric Current is the most familiar entity in any Electrician’s Life.

Their entire profession revolves around managing the current flow in various electrical equipment, appliances, and complex wirings. Their expertise lies in ensuring that the supply and demand of electric current are accurately met for the proper functioning of almost every electrical circuit around us.

The implications of anything going wrong in this management are almost unthinkable. It may lead to loss of revenues in commercial places, loss of momentum in home chores, hindrances in educational activities, and most importantly chances of fatal damages to people and places. It is apt to consider present-day Electricians as Masters in Current management.

But such huge responsibility comes with fatal risks to personal and public life.
Also called the Electricians Best Friend, the Voltage Detector is the primary tool that helps an Electrician to suspect a potential electric risk.

The Voltage Detector is electronic equipment specially designed to identify live voltage points in the test appliances. Such open voltage points are the primary source of sudden electrical shocks and short circuits that are fatal and can wreak havoc when non checked.

Using Voltage tester on potential shock points is only the initial step to any electronic repair but its utility can not be compromised.

In some instances, electricians have faced injuries while using voltage testers during repair work. These injuries happened either due to insufficient insulation of voltage testers or minor direct contact of Electricians with shock points.

To counter and overrule such dangerous instances, engineers have come up with an advanced testing facility that is well insulated and requires zero contact with potential risk points to take voltage readings. This advanced testing facility is termed as Non Contact Voltage Testers and is an exceptionally preferred choice among professional electricians.

Non-Contact Voltage Detectors are designed in such a way that they utilize capacitive current to sense even the minute changes in the electric field caused by nearby Alternating current. This ensures that no metallic touch is necessary to measure the reading of live voltage. The only contact required is the touch on the handle top to complete the circuit loop with earth source.

Upon this touch, if the indicator visual or audio sensor activates or beeps; this verifies the live presence of current in the conductor.

These devices require minimal extra energy to run the voltage indicators or work lights, please note that this energy does not flow through the user’s body hence guarantees safety.

We understand that picking up the perfect tool can be a lengthy task. Hence, we came up with this comprehensive blog to help you make an informed decision with the help of our curated list and a buying guide to help you understand the technicalities associated with the purchase of electrical voltage testers.

Buying Guide

Since many of you were hopping from one website to the other in the search for the best tool for your personal or professional requirements, we have compiled a well-researched blog to help you make the final decision.

This blog consists of a list for the best 15 voltage testers available in the markets and an essential Buying Guide to provide you an overview of technicalities related to buying the right tool.

Now that you have already checked out our list of top 15, through this buying guide; we would like to give you an overview as to what all you should look for and prioritize before concluding your shopping for the right testing tool.

Why should anyone read the buying guide first?

Well, there are three major reasons:

• It helps you understand the product and its accessories, which you wish to buy, in a comprehensive way.
• It helps you do the comparative analysis of all products with their competitors which eventually leads to an informed decision.
• It will save you enormous time, money, and miscellaneous mental stress.

Without taking your time further, let’s take a look at the most important factors to help you decide the perfect tool for you.

Portability

To enjoy comfort and convenience during your hectic work routine, you must go for a voltage tester pen. This will enable you to freely carry and hold it while climbing on a ladder or driving. The easy option to clip it near your collar or pocket is an added advantage and keeps your favorite tool near your heart.

Another factor to consider is that not all electric tools are meant to be purchased by professionals. Some are ideal for students, homeowners, and DIY enthusiasts who may not need to carry voltage testers the entire day with them. Therefore, Voltage testers that come as Multimeters or with GFCI outlet testers have their own set of purposes.

Choice of Material

The utility and effectiveness of an electrical tool significantly depend upon the material construct of the tool.

The hard plastic made voltage testers will definitely be ultra-lightweight but may lead to deformed shape in the long term usage. Hence, for robust built and durability you shall choose the ABS polycarbonate resin material which comes with a slip-free comfy grip.

No matter what material you choose, it should ideally be resistant to mechanical force, rain corrosion, dust, and oil slips.

Durability

Some products in our top 15 list are elegantly designed and yet will pass the durability tests. Although no matter how elegant an electrical tool is, the money invested is only fruitful when the product is durable.

Another point to be noted while analyzing the durability of electrical tools, especially Non-Contact voltage testers is that heavy usage may result in unexpected wear and tear, or damage in delicate parts like LCD, dead battery, or the insensitivity of a narrow tip which checks the voltage.

Therefore, make sure your choice is robust and sturdy if it means shedding a few extra dollars.

Maintenance

Durability and Maintenance are intricately linked to each other.

With proper maintenance, even the most delicate products tend to live and perform a little longer than expected. Keeping your voltage tester away from corrosive environments like rain and avoiding dust is a must-do job. It is preferable to avoid dropping your electrical tool from heights more than 10 feet and being crushed underweight more than 250 pounds.

Non Contact Voltage tester comes in the dainty category of electrical tools. Make sure to invest money on a tester that has a sturdy LCD and reliable battery to help you redeem your investment.

Price

The most significant of all, the price!

Most of the popular and successful products are manufactured by well-reputed market leaders and engineers. Their expertise may come with a price but also with precious reliability. A higher price may signify a well-established brand or inclusive accessories as a cost-benefit for you.

Make sure to check the manufacturer brand and the included components in the shipped package to get a clearer idea of cost distribution.

Final Words

Finally, we would like to conclude this blog on the same point from where we started this blog that “Electric Current is the most familiar entity in any Electrician’s Life.”

And in this professional life, if you will spend maximum time with any particular tool, It is the Voltage Tester!

Therefore, before you make the final click, we would suggest you not compromise on your safety, not compromise on the durability of the product, and not hesitate in purchasing your favorite product even if this all requires you to shed only a few extra bucks.
