Hioki SM7420

  • Super Megohm Meter. 4ch micro current model - perfect for automated-systems integration.
  • 300 times better noise resistance
  • 6000 ps/minute - ideal for mass production

Super Megohm Meter

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.

  • Large triaxial connector (approx. 16 mm (0.63 in) in diameter) that supports high-capacity output of 2000 V (2 mA) or 1000 V (10 mA) ensures both safety and functionality
  • Triaxial TNC connector brings out the measuring characteristics of the instrument by reducing, instrument by reducing the effect of the noise in the working environment and allowing for stable measurement at a maximum of ±10 dgt.

From high-volume production of 1600 units per minute to high-precision evaluation of semiconductors

 

2000 V microcurrent measurement

With a single instrument, you can measure protective semiconductor elements such as varistors, vehicle capacitors, and other high-voltage components.

This SUPER MEGOHM METER applies voltage from 0.1 V to 2000 V and measures with a resolution of 0.1 fA.

Embedded in the line for reliable high-speed and "high-performance" contact checks

Measure small-capacity components

Lowest threshold value setting of 0.1 pF

The super megohm meter allows you to perform reliable contact checks on low-capacity capacitors as well as on other measurement objects with small capacitance.

With multiple various measuring instruments

2-band selection

To prevent the check signals on a production line with multiple various measuring instruments from getting crossed, select the measurement frequency for contact checks.

In ammeter mode

Compatible with external power sources

The contact check function is also available when you use the instrument as an ammeter with an external power source. The instrument is also suitable for measurements over 2000 V.

When changing cables on-site

Cable length correction function

To replace a cable, simply register the measur ing cable length. Time-consuming adjustments are no longer necessary and the instrument can be used for changing the line in a flexible manner.
