The FLUKE 1AC-II VoltAlert™ Non-Contact Voltage Detector provides a fast, safe and reliable way to check for the presence of AC voltage without direct contact with live conductors. Simply touch the tip to a terminal strip, supply wire or outlet – the entire tip glows red and emits an audible beep when voltage is detected.
Designed for electricians, maintenance technicians, safety personnel and homeowners, this detector senses the steady-state electrostatic field produced by AC voltage through insulation. With a CAT IV 1000V safety rating, it delivers professional-grade protection for both light-duty and heavy-duty applications.
Its built-in self-test feature continuously checks battery and circuit integrity with a periodic double flash, ensuring the device is always ready for use. Operating reliably between -10°C and +50°C, the FLUKE 1AC-II is ideal for workshop, industrial and household environments.
Learn the basics of electrical testing, including safe voltage measurement and circuit troubleshooting techniques.
A non-contact voltage tester is used to safely detect the presence of AC voltage in outlets, cables, switches and terminals without touching live conductors. It is ideal for checking if a circuit is live before performing electrical work.
It works using capacitive coupling. When brought near an AC conductor, the tester detects the changing electric field around the wire. The user holding the tester provides a ground reference, allowing the device to sense voltage without direct contact.
Yes. With a CAT IV 1000V safety rating, it provides high-level protection suitable for industrial, commercial and residential applications.
The FLUKE 1AC-II detects AC voltage between 200V and 1000V, making it suitable for a wide range of electrical testing applications.
Very little maintenance is required. Simply wipe it clean after use and replace the AAA batteries when needed to ensure reliable performance.
