Megohmmeters - Insulation Testers

Why Choose AEMC® Instruments Megohmmeters?

Complete Line of Megohmmeters

We know it’s essential for you to have the ability to properly determine the condition of the insulation on wire and motor windings to prevent damage of expensive equipment and unplanned shutdowns as well as ensure personal safety. That’s why we offer a full line of Megohmmeters with test voltages from 10V to 15kV (model dependent), capable of measuring insulation resistances from 1000 to 30TΩ. These rugged, weather resistant meters are accurate, reliable and built to perform. Battery, AC powered, and hand-cranked models are available.

Covering the Spectrum of Insulation Resistance Testing

Routinely using a megohmmeter to check both new installations and as a maintenance program helps to ensure your circuits are safe. Our instruments offer high-resistance testing up to 30TΩ. AEMC megohmmeters perform spot, timed, step voltage, and ramp voltage testing to measure resistance, Dielectric Absorption Ratio (DAR), Polarization Index (PI) and Dielectric discharge (DD).
