Extech MG302 Digital Multimeter & Insulation Tester

This product has now been discontinued. Please see the Extech MG320 Insulation Multimeter for a suitable replacement.

The Extech MG302 is a combined digital multimeter and insulation tester that measures insulation resistance from 0.001MΩ to 4000MΩ at four different test voltages.

This fully featured TRMS multimeter has a rugged housing that is waterproof to IP67, displays results on a large backlit LCD and also offers a Lock Power On function that enables hands-free operation.

In addition, the Extech MG302 multimeter has a built-in datalogging function that allows readings to be stored and then wirelessly transferred to a PC or laptop for further analysis. The MG302 is the perfect digital multimeter & insulation tester for electrical contractors as well as HVAC engineers and plant/facility PDM managers.
