The Extech MG300 is a 13 Function Wireless True RMS MultiMeter/Insulation Tester. 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. The CAT-IV-rated meter's wireless datastreaming 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.
