Non-Contact Voltage Tester GVD-3504

The Gardner Bender GVD-3504 Circuit Alert detects AC voltage from 50 to 600 volts without touching live conductors. Audible beeps and a 360-degree flashing red light signal the presence of voltage. A fully insulated probe tip removes the risk of accidental contact. The tester carries C/ETL/UL listing and a CAT III 600V rating.

Verify Power and Compatibility

Confirm the circuit you intend to test falls within the 50 to 600 volt AC range. The unit requires one AAA battery which is not supplied, so have a fresh cell ready before first use. Ensure the built-in safe-test function operates correctly each time you power the tester on. The compact body measures 5.5 by 2.9 by 9.75 inches and includes a pocket clip.

Suited for Electrical Safety Checks

Electricians, maintenance technicians and DIYers who need quick, non-contact confirmation of live wires will find this tool practical. It is not intended for DC voltage measurement or for circuits outside the stated AC range. Buyers who require a contact multimeter with resistance or continuity functions should look at a different instrument class.

Questions about this item

Does the GVD-3504 come with the AAA battery it needs, or must I buy one separately?

The tester requires one AAA battery which is not included, so you will need to purchase it separately before use.

How do I know the 50V to 600V detection range on the GVD-3504 is right for the circuits I work on?

That range covers typical residential and light-commercial AC circuits; the tester beeps and flashes a 360° red light whenever voltage in that window is present.

What does the built-in safe-test feature on the GVD-3504 actually verify before I trust a reading?

Pressing the safe-test button confirms the tester’s circuitry and the installed battery are both working, giving a positive beep and flash if they are functional.
