Extech MG300 Insulation Tester / Multimeter with Wireless PC Interface (915MHz)

The MG300 is a True RMS multimeter with built-in insulation resistance tester with the added safety of wireless data streaming for remote monitoring and datalogging. By adding insulation testing capabilities to the ubiquitous digital multimeter, electricians are always equipped for insulation testing, helping to make it a more routine part of predictive maintenance with faster troubleshooting and repairs without additional tools.

Features Overview

The rugged and waterproof (IP67-rated) combination meter includes a digital insulation resistance tester (or megohmmeter) with 4 different test voltages for measuring resistance up to 4 GΩ with 0.001MΩ resolution. The full-function, true RMS digital multimeter includes useful extras like duty cycle measurements and milliamp readings for analog 4-20mA current loops in industrial analog process controls. The CAT IV-rated meter’s wireless data streaming enables safer troubleshooting and maintenance on dangerous moving equipment and one-person operation of remote safety switches. Technicians can focus on finding problems by monitoring real-time readings on a laptop or computer screen from safe distances – up to 30 feet away.
