Work with electrical equipment and systems as an electrician, contractor, handyman, or DIY enthusiast?
If so, you are aware of how crucial it is to have a trustworthy voltage tester that can assist you in checking the voltage or de-energization of outlets or circuits, testing the continuity and phase rotation of wires, and ensuring the security and caliber of your electrical installations.
By avoiding electrical risks and failures, a voltage tester is a crucial tool that can save you time, money, and hassle.
However, how do you pick the best voltage tester for your requirements? There are several things to take into account, including the voltage tester’s features, functionalities, accuracy, dependability, durability, safety, and pricing.
To determine which one gives the best performance and value, you should also examine several brands and models. If you are unfamiliar with the technical requirements and standards of voltage testers, this work may seem difficult.
Because of this, we wrote this post to assist you in selecting a voltage tester with knowledge. The testo 750-3, testo 750-2, and Kyoritsu KT 171 are three well-known and trustworthy voltage testers that will be compared in this article.
All of these voltage testers have LEDs and LCDs and can test AC and DC voltages up to 690V. They are also appropriate for phase rotation testing, continuity testing, and single pole voltage testing. However, they do differ in a few ways that affect how well they suit various needs and preferences.
Without further ado, let’s begin comparing the three voltage testers: the Kyoritsu KT 171, the Testo 750-2, and the Testo 750-3.
The most sophisticated of the three is the testo 750-3 voltage tester, which is perfect for professionals who need a reliable instrument.
It includes a 3-digit LCD display that provides the precise voltage reading, which is highly helpful for problem-solving and problem-diagnosis.
For instance, you may quickly determine the source and solve the issue if you are checking a circuit breaker and see that the voltage is either too low or too high.
In order to assess the safety of electrical installations—which is crucial for avoiding accidents and injuries—the testo 750-3 also offers a GFCI test capability.
For instance, you can use the Testo 750-3 to check if an outlet in your kitchen or bathroom has a ground fault circuit interrupter (GFCI) that guards against electric shocks if you are testing it and discover that it is not functioning properly.
Additionally, the testo 750-3 has a built-in flashlight, a visible LED voltage indication that can be seen from all sides, and a vibrating load button that make it simple and secure to use in any circumstance.
The LED voltage indication shows you the presence of voltage clearly and distinctly with large fiber-optic illuminators that are visible from any angle, the flashlight improves your night vision, the vibrating load button makes sure you’re testing the voltage and not inadvertently pressing the wrong button.
The testo 750-3 voltage tester is the most sophisticated and dependable device available, and it is well worth the price.
For technicians who require a dependable and adaptable instrument, the testo 750-2 voltage tester is a suitable choice.
For assuring compliance and high standards, it offers a GFCI test function that may evaluate the security of electrical installations.
For instance, you can use the testo 750-2 to check if the outlets have GFCI protection, which prevents fires and shocks, if you’re working on a construction site or restoration project and need to make sure the electrical wiring is done correctly and safely.
The testo 750-2 is also equipped with an integrated flashlight, a visible LED voltage indication that can be seen from all sides, and a load button that vibrates, making it dependable and practical to use in a variety of settings.
The LED voltage indication shows you the presence of voltage clearly and distinctly with large fiber-optic illuminators that are visible from any angle, the flashlight improves your night vision, the vibrating load button makes sure you’re testing the voltage and not inadvertently pressing the wrong button.
With the exception of the LCD display, the testo 750-2 voltage tester is a close second to the testo 750-3 model in terms of features. The testo 750-2 may be adequate for your needs if you don’t require the precise voltage value and are content with only viewing the voltage range with lights.
For those who are just starting out and require a straightforward instrument, the Kyoritsu KT 171 voltage tester is a respectable choice. It contains LCDs and LEDs that display the voltage range, which is adequate for the majority of everyday applications.
The Kyoritsu KT 171 can be used, for instance, to quickly determine whether a light switch or lamp is on or off by testing the voltage with lights or numbers.
The Kyoritsu KT 171 has two functions in one model:
measuring without batteries and self-test. It also has a penlight, a unique design with big, bright LEDs. The penlight improves your night vision, but it is not as strong as a flashlight.
The Kyoritsu KT 171 has a unique design that makes it look stylish and contemporary, but unlike the testo versions, it lacks an all-around viewable LED voltage indication.
With the two features of this model, you can measure voltage without a battery or run a self-test to ensure that all the LEDs are functioning properly.
Although not a bad voltage tester, the Kyoritsu KT 171 lacks some of the features and functions that set the testo models apart. For instance, it lacks a GFCI test feature, which is essential for testing outlets in wet or damp situations and can assess the safety of electrical installations.
Additionally, it lacks a vibrating load button, which is a very helpful feature for preventing mistakes and errors and ensures that you are testing the voltage and not inadvertently pressing the wrong button.
Three well-known and respectable voltage testers, the Kyoritsu KT 171, the testo 750-2, and the testo 750-3, have been compared. All of these voltage testers have LEDs and LCDs and can test AC and DC voltages up to 690V.
They are also appropriate for phase rotation testing, continuity testing, and single pole voltage testing. However, they do differ in a few ways that affect how well they suit various needs and preferences.
Each voltage tester’s features and functions have been thoroughly explained, along with the benefits and drawbacks of each. You have also received our advice regarding which of the three voltage testers is the best option. Here is an overview of our comparison and advice:
