Hioki SM7420 4-Channel Super Megohm Meter

The Hioki SM7420 is a 4-channel simultaneous super megohmmeter that supports applications for improving the productivity of passive components such as capacitors and filters.

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.
