Megger AVO840 TRMS Digital Multimeter – 1000V | Low-Z, Bluetooth & IP44 Rugged Design

Megger AVO840 TRMS 1000 V AC/DC Digital Multimeter overview

The Megger AVO840 TRMS Digital Multimeter is a professional-grade diagnostic tool designed for industrial electricians, HVAC specialists, service engineers, and renewable energy technicians.

Unlike standard multimeters, the AVO840 stands out with its Low-Z mode that eliminates ghost voltages — a common problem in live and complex electrical environments. This ensures accurate, stable, and safe readings even in distribution panels, motor control centers, and modern electronic systems.

The instrument provides a comprehensive measurement range, covering AC/DC voltage up to 1000 V, current up to 10 A, resistance, continuity, capacitance (up to 6000 µF), diode checks, frequency, duty cycle, and temperature measurement with a K-type thermocouple.

Connectivity is a game-changer with built-in Bluetooth support. Pair the meter with the Megger AVO Link app (iOS & Android) to log data wirelessly, generate trend graphs, and share reports instantly with colleagues or clients.

Built for harsh environments, the AVO840 features IP44 ingress protection, is drop-tested to 2 meters, and housed in a rugged double-moulded case, ensuring reliability in demanding fieldwork. Its 6000-count backlit LCD with analogue bar graph provides fast, intuitive visualization of fluctuating signals, even in poor lighting.

Whether you’re working in industrial power systems, HVAC diagnostics, renewable energy setups, or electrical panel testing, the Megger AVO840 combines precision, durability, and connectivity to deliver professional results every time.
