Extech MG300

13 Function Wireless True RMS MultiMeter/Insulation Tester

The Extech MG300 is a True RMS Multimeter with a built in insulation resistance tester that features 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. This feature helps make the MG300 a more routine part of predictive maintenance with faster troubleshooting and repairs without additional tools. 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 4G Ω with 0.001 MΩ resolution. Complete with remote receiver with USB cable, windows compatible software, heavy duty test leads, alligator clip test lead, Type K bead wire temperature probe with adapter, carrying case, and 6 AA batteries.
