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.

• 300 times better noise resistance
• 6000 ps/minute - ideal for mass production
• 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.
