Voltage testers are special devices used to detect and measure the amount of current flowing in a circuit. These items incorporate expert construction, ensuring that the user is safe while dealing with any tools and wires, including the live wires. Thus, if you need a device to detect the presence of current, you should look for one of the best voltage testers.
These testing devices have screens or scales which indicate the actual amount of the voltage in the circuit. Thus, you will not have to perform any guesswork. However, they combine different constructions for different situations. For example, a voltage tester to be used by homeowners is different from a voltage detector for the manufacturers. Thus, you need to be acquainted with knowledge before setting your foot to purchase these items. To help you, we will first check on the most sought-after voltage testers.

Buying Guide for the Best Voltage Tester
Voltage testers are handy tools in detecting and measuring the amount of current flowing. Nonetheless, we can’t overlook the accompanying electric risks, especially when dealing with live wires. Additionally, there are different types of voltage testers which might make it hard to tell which item suits your situation. For that reason, we are going through this detailed buying guide that will help you acquire a great deal of information about how to choose the best voltage tester.
What Are Some Detecting Techniques of the Voltage Testers?
Voltage tester uses two main techniques to detect and measure the voltage in circuits that categorize them as contact or non-contact testers. With the contact testers, you will have to bring the tester into contact with the circuit. Fortunately, some of the contact voltage testers have clips to attach to the wire.
When it comes to non-contact testing, you do not have to perform any connections because the voltage tester has a high level of sensitivity to detect the current at proximity.
What Are the Different Types of Voltage Testers?
Inductance testers are non-contact voltage testers that are the safest testers on the market. They detect the current without having to get into contact with the circuit. Thus, they are the best for testing voltage in live wires. These types of testers usually use batteries and have LEDs on the tip to notify you about the presence or absence of the voltage. Hence, they would also be best for you if you hate reading the scales.
Neon voltage testers
The neon voltage testers are small-sized devices with metal probes on both ends. These detectors do not use batteries, making them more reliable. However, they only detect the voltage but do not give the actual measurements. To use these voltage testers, you should place one of the probe’s ends to the wire and the other end to a neutral ground. If the current is flowing, then the neon light on the bulb will light up.
The continuity testers are devices that are specially made to test a dead circuit. Thus, these devices should only be used when the circuit is switched off or disconnected. They use batteries and have a probe at one end and a cord attached to a clip to connect to the circuit.
If you have multiple electric measurements to take besides voltage, the multimeter will be the best. This is because this device is versatile in its uses and can give multiple electric readings such as frequency, resistance, capacitance, continuity, direct current voltage, and alternating current voltage. However, most people dislike this voltage tester because it doesn’t have any alarm, flashlight and even its scale is slightly complex. But, this voltage tester would be the best choice if you need multiple measurements with a high level of accuracy.
Digital clamp meter
This electric tool is only common to professionals, and also it is more expensive than the other voltage testers. However, it combines the functionalities of a voltage tester and a current sensor. Consequently, it gives multiple electric readings and can detect the current flow at a far distance. Moreover, this device has clamping jaws to grip the wires, making them safer than a multimeter.
What Features Should You Look for When Purchasing a Voltage Tester?
Voltage testers have different voltage ranges. For instance, some testers can only test within a range of 12v to 1000v, while others have a testing range of 60v to 1000v. To determine your voltage requirement you should first determine the use of the voltage tester. If you are dealing with extremely high voltages, for instance, in industrial circuits, then the scale of the testing device should be as large as possible. Similarly, if you need to detect the most minimal voltage, the multimeter scale should accommodate lower values.
Some voltage testers, such as a multimeter, have scales that you should read to get the actual measurements. Thus, if you have a complicated scale, you will take hours to do a single reading, and worse, you are at a higher risk of getting the wrong measurements. Hence, you should ensure that your scale is easy to read and does not require any prior calculations to have the correct reading.
LED and LCD
Voltage testers with LED and LCD have the most user-friendly operations. The LED lights indicate the presence or the absence of the current. Even better, in some detectors, the LED brightness increases according to the intensity of the current. For instance, if the current is low, then the light will be dimmer. Besides voltage testers with LCD screens allow you to quickly read the measurements. Hence, they are becoming sought-after these days because of the convenience they offer.
Lastly, you should also look at the casing of the voltage tester. It should incorporate a sturdier construction that can absorb impacts in case the voltage tester falls. Additionally, its surface should give the user a firmer grip to prevent it from slipping out of their hands.
How Do You Test Live Wires?
Handling live wires needs you to be more careful to avoid the risk of an electric shock. We don’t have to remind you that electric shocks are pretty deadly. Similarly, when testing a live wire, you need a highly improved tester that meets the ETL safety standards.
To test a live wire, you need a non-contact voltage tester or a pen voltage tester. The non-contact voltage testers detect the current at a far distance. Hence, you will only place it at proximity, and it will detect if any current is flowing in the wire.
On the other hand, we have the tester pens. These voltage testers have tips that you place on the wire while holding on the far end. The tester pens have LED which lights differently in the presence or absence of the current, and an LCD screen where you take your reading.
Voltage Tester FAQ
Q: Is a voltage tester the same as a circuit tester?
A: A circuit tester is a device that checks if the circuit is well connected, while a voltage tester only detects if the wire has current. Hence, these devices are very different.
Q: Can I use a voltage tester on a live wire?
A: You can test the voltage on a live wire using a non-contact tester. Thus, you do not have to hold the live wire or perform any connections to detect the voltage.
Q: How do I know that the voltage tester promises my safety?
A: The most secure way of ensuring that you have a safety-promising voltage tester is checking on the ETL certification. ETL is an international program that tests the durability, reliability, and safety standards of electric items.
