10 Best Non Contact Voltage Testers 2026 in the United States

The Fluke 1AC II VoltAlert Non-Contact Voltage Tester is a compact and reliable tool for detecting voltage presence. One of its notable strengths is its wide voltage detection range of 90 V to 1000 V AC, making it suitable for various electrical applications. The indicator system is user-friendly, featuring a red glowing tip and an audible beeper to signal voltage detection, ensuring clear and immediate alerts.

For added convenience, users can switch between audible and silent modes based on their working environment or preference. Additionally, the continuous self-test function enhances reliability by confirming the tester is always operational. Safety is a key focus with its CAT IV rating, ensuring it meets high standards for industrial and commercial use. Durability is supported by a 2-year warranty, and the compact, pocket-sized design enhances portability.

However, the tester relies on two AAA batteries, which are included, but users need to ensure they have replacements on hand. Also, while the device is lightweight, weighing only 59 grams, its plastic construction may not be as robust as some heavier-duty models. The Fluke 1AC II offers an excellent balance of functionality, safety, and portability, making it a strong choice for electricians, DIY enthusiasts, and anyone needing a reliable non-contact voltage tester.

The Klein Tools 80064 AC Circuit Breaker Kit is a comprehensive 3-piece kit that includes a digital circuit breaker finder, a non-contact voltage tester pen, and a convenient zipper bag to keep everything together. This kit is particularly useful for those who need to accurately identify circuit breakers and detect voltage in various electrical components such as cables, cords, and switches.

The digital circuit breaker finder is quite precise with its visual and audible indicators, making it easier to locate the correct breaker. The non-contact voltage tester pen features bright green LEDs to indicate power and red LEDs with a tone to signal the presence of voltage, enhancing safety and usability.
