Gardner Bender Gvt-392 Solenoid Voltage Tester, 120-480v Ac/dc

The Gardner Bender GVT-392 is a solenoid voltage tester designed for electricians and maintenance professionals who need fast, reliable voltage detection in tight or crowded electrical panels. This handheld tester identifies the presence of AC and DC voltage without requiring you to look at a display—a vibrating solenoid alerts you tactilely when voltage is detected, making it ideal for one-handed operation and safer troubleshooting in confined spaces.

Whether you are testing outlets, circuit breakers, light fixtures, switches, extension cords, or electrical panels, this tester gives you three ranges of voltage indication and dual confirmation of your results. The solenoid vibration tells you voltage is present, while a neon light bulb displays DC polarity status, so you get both tactile and visual feedback in a single tool.

Features and Benefits

• Solenoid Vibration Alert: Feel the vibration when voltage is detected, eliminating the need to watch a gauge or screen during testing.
• Neon Polarity Indicator: A built-in neon bulb shows DC polarity status at a glance, providing quick visual confirmation.
• Extended Reach: 26-inch leads allow you to test voltage in crowded panels and hard-to-reach locations safely from a distance.
• Rugged Construction: High-impact, dual-insulated case withstands heavy job-site use and accidental drops.
• One-Hand Operation: Built-in probe slots hold the leads for convenient single-handed testing and compact storage between jobs.
