The AV40DC Voltage Detector from Bierer Meters is a direct contact voltage indicator designed for utility professionals working across a range of energized environments. With an operating range from 120 volts to 40 kilovolts, it provides both audible and visual alarms to signal the presence of voltage. This tool is suitable for use on secondary systems, underground residential distribution (URD), and overhead transmission lines. Its built-in test position ensures reliable performance before and after each use, supporting safety compliance in field operations.

Engineered for durability and field readiness, the AV40DC includes a universal grip-all adapter and is packaged in a rugged carrying bag. The unit is water-resistant and features super-bright LEDs and an ultra-loud horn for clear indication in noisy or low-visibility conditions. It is ideal for linemen and electrical workers performing voltage verification on capacitive test points, elbows, and conductors in both underground and overhead systems.
