Extech MG302 Insulation Tester / Multimeter with Wireless PC Interface (433MHz)

Designed for users outside of North America because of its 433 MHz wireless transmitter frequency, the MG302 is a true RMS multimeter with built-in insulation resistance tester with the added safety of wireless data streaming for remote monitoring and data recording. By adding insulation testing capabilities to this CAT IV-rated digital multimeter, electrical troubleshooters will always be equipped for insulation testing, helping to make it a more routine part of predictive maintenance with faster troubleshooting and repairs without the need for additional tools.

MG302 Features Overview

The rugged and waterproof (IP67-rated) combination meter includes a digital insulation resistance tester (or megohmmeter) with four different test voltages for measuring resistance up to 4 GΩ with 0.001 MΩ resolution. The full-function, true RMS digital multimeter includes useful extras, like duty cycle measurements and milliamp readings for analog 4-20 mA current loops in industrial analog process controls. The MG302 also has built-in wireless data recording for safer troubleshooting and maintenance on moving equipment, one-person operation of remote safety switches, and the ability to monitor real-time readings on a laptop or computer screen from safe distances — up to 30 feet away — to detect intermittent anomalies.

Applications

Insulation testers can be used to test motor, transformer windings, instruments, and appliances, check for moisture in wire and cable assemblies, safely evaluate a new wiring installation, and check for carbon tracking in breakers, relays, and switches. Extech Insulation Testers offer high sensitivity to assure reliable monitoring of low resistance motor windings.
