Gardner Bender GVT-392 AC/DC Vibrating Solenoid Voltage Tester, 120 - 480V with DC Polarity and Neon Indicator

Gardner Bender GVT‑392 AC/DC Vibrating Solenoid Voltage Tester

The GVT‑392 is a handheld voltage tester that uses a vibrating solenoid mechanism to give tactile feedback when voltage is present. It includes a neon indicator that lights up to confirm a live circuit. Designed for both AC and DC applications, the tester works within a voltage range of 120 V to 480 V. The device is suited for checking DC polarity as well.

Key Features

• Detects AC and DC voltage up to 480 V
• Vibrating solenoid provides a physical indication of voltage presence
• Neon light illuminates when voltage is detected
• Supports DC polarity testing

To use, bring the probe into contact with the conductor or terminal. When a voltage is present, the solenoid vibrates and the neon indicator lights. The combination of a visible light and a vibrating signal helps identify energized lines quickly and safely.
