HIOKI SUPER MEGOHM METER SM7420
4ch micro current model - perfect for automated-systems integration
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. The SM7420 is industry's fastest 4-channel simultaneous super megohm meter that supports applications for improving the productivity of passive components such as capacitors and filters.
Characteristics of the MLCC Leakage Current Test System
This high-speed test system combines the 4ch microcurrent SUPER MEGOHM METER SM7420 with an external power source, or the 8ch SUPER MEGOHM METER SM7810, developed for leakage current tests, with a 32ch output POWER SUPPLY UNIT SM7860.
Perfect for equipping on automated machines, use this to construct the fastest MLCC leakage current inspection line.
[Low capacity contact checks]
The SM7420 is equipped with contact checks that can identify low-capacity capacitors of only a few pF as well as measured objects with a small capacitance.
(Reference value: 0.1 pF to 99.99 pF)
[CH independent contact checks]
The SM7420 using an external power source enables check frequencies and delay settings to be changed for each measurement channel, achieving detailed settings that match the line design.
Stability (repeatability) against power supply noise and external noise has improved dramatically due to a combination of new Super Megohm floating circuitry and triaxial connectors.
Variability in normal usage environments is reduced to 1/60 compared to previous models, and to 1/300* in conditions where 50 V noise is applied.
