The new MG300 from Extech Instruments is a true-rms multimeter with a built-in insulation resistance tester. The instrument’s wireless data streaming provides added safety to users, who can monitor real-time readings on a laptop or computer screen from up to 30 ft away.
By adding insulation-testing capabilities to a DMM (digital multimeter), Extech has made it easier for electricians to make insulation testing a more routine part of predictive maintenance. The waterproof combination meter includes a digital insulation-resistance tester (or megohmmeter) with four test voltages for measuring resistance up to 4 GO with 0.001-MO resolution. The full-function DMM includes duty-cycle measurements and milliamp readings for analog 4–20-mA current loops in industrial analog process controls.
The MG300 meter includes a remote USB receiver and Windows-compatible software and is available with NIST-traceable certification. For users outside North America, Extech has introduced the MG302, which transmits data at 433 MHz instead of 915 MHz. More Information Product web page
