Description

Megger AVO850 – TRMS Digital Multimeter with Bluetooth Overview

The Megger AVO850 True-RMS Digital multimeter is a premium-grade instrument engineered for electricians, field engineers, and industrial maintenance teams who demand accuracy and durability. Built with Megger’s trusted reliability, this industrial multimeter is ideal for HVAC system testing, power distribution diagnostics, renewable energy verification, and complex troubleshooting.

Precision with True-RMS Technology

Unlike basic testers, the AVO850 uses True-RMS measurement to provide accurate AC readings on distorted or non-linear waveforms, such as variable frequency drives (VFDs), motor controllers, and harmonics-heavy circuits. With ranges up to 1000 V AC/DC and 10 A current, it delivers consistent results even in the most challenging environments.

Professional Features for Efficiency

Engineered for versatility, the AVO850 multimeter consolidates multiple tools into one device:

Measures AC/DC voltage, current, resistance, continuity, capacitance, frequency, duty cycle, diode test, and temperature.
6000-count backlit LCD with analogue bar graph for clear visualization.
Advanced functions: Min/Max/Avg capture, Peak Hold, Relative mode, and Data Hold.
Auto-ranging with manual override for faster testing.

This makes the AVO850 a True-RMS tester suitable for both everyday electrical checks and advanced industrial diagnostics.

Safety and Rugged Design

Safety is non-negotiable in professional environments. The Megger AVO850 is certified to CAT IV 600 V / CAT III 1000 V, compliant with IEC 61010-1 standards. A double-moulded, impact-resistant housing provides extra protection against drops and harsh site conditions, while its ergonomic, compact design ensures comfortable use in the field.

Why Choose the AVO850?

Trusted Megger brand with a reputation for professional-grade instruments.
Combines industrial reliability with modern usability.
Designed for preventive maintenance, commissioning, and troubleshooting.
Perfect upgrade from entry-level or mid-range multimeters for engineers seeking long-term durability.
