Key Features of the 4CH Microcurrent Measurement Super Megohm Meter SM7420
The 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 from Hioki 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.

- Channel-independent low capacity contact check
- Perfect for equipping on automated machines
- Max. 2 × 10^19 Ω display
- Min. 0.1 fA resolution
- Built-in EXT I/O, RS-232C, GP-IB and USB
HIGH-PERFORMANCE CONTACT CHECKS
[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.
1/60 VARIABILITY, 300X NOISE RESISTANCE
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.
