Pocket-Sized Voltage Detection for Electricians

The Fluke 1AC II VoltAlert is a non-contact AC voltage tester designed for electricians, maintenance staff, safety personnel and homeowners. It detects voltage from 90 V to 1000 V AC simply by touching the tip to a terminal strip, outlet or supply cord. The tip glows red and an audible beeper sounds upon detection. A continuous self-test ensures the tool is always ready for use.

Check Your Measurement Range and Safety Rating Needs

Verify that the 90 V to 1000 V AC detection range covers the circuits you intend to test. Confirm that a CAT IV 1000 V rating matches the safety requirements of your work environment. The tester operates on two AAA alkaline batteries, which are included, so ensure you have replacements available for continued operation. Consider whether you need the lower 20 V to 90 V AC control circuit model instead.

Upgrade from Basic Testers Lacking Self-Test

This unit replaces simple voltage pens that lack continuous self-test verification or a high safety category rating. The jump is worth it when you need immediate confirmation that the detector itself is functioning before each use. It also upgrades tools without audible alerts or a bright tip glow, providing clearer indication in noisy or dim conditions. The pocket-sized form factor adds portability for daily carry.

Questions about this item

Does the tester ship with batteries or do I need to buy them separately?

Two AAA alkaline batteries are included so the unit works straight out of the box

Which voltage range should I choose for household wiring versus industrial panels?

The 90 V to 1000 V AC range covers standard mains circuits while the 200 V to 1000 V AC option suits higher-voltage panels

What does the CAT IV 1000 V rating mean when I am testing a live circuit?

It certifies the tester for measurement category IV up to 1000 volts, providing protection against transient over-voltages at the service entrance
