HIOKI SUPER MEGOHM METER SM7120

Rapid 6.4ms Super Megohm and Low Current Testing

The Hioki SM Series Super Megohm Meters are high resistance and ultra low current inspection devices with a 0.1 fA resolution to offer precise testing on production lines. To accommodate vehicle components with increasingly high breakdown voltages, the SM7120 is the first insulation tester in the world to be able to output a measurement voltage of 2000 V.
