Description

The Extech MG320 is a versatile tool designed for professionals who need both high-accuracy insulation testing and reliable multimeter capabilities in one portable device. This dual-function unit provides a 20G Ohm/1000V insulation tester alongside a True RMS multimeter, making it an efficient choice for electrical testing and maintenance tasks. With built-in PI and DAR modes, the MG320 helps you assess insulation quality through polarization index and dielectric absorption ratio measurements. The integrated programmable timer allows you to set specific test durations, while the comparator feature enables custom configurations for faster, more accurate results. Safety is a priority with a Cat IV 600V rating and clear indicators for high voltage and overloads. This kit is ready for immediate use, coming complete with test leads, an alligator clip, a soft carrying case, and the necessary 6 AA batteries. Whether you are performing low resistance measurements with the zero function or managing data with the ability to store and recall up to 99 readings, the MG320 delivers the performance you need in a compact form factor.
