SUPER MEGOHMMETER SM-8213, SM-8215, SM-8220
Super Megohm Measurement in Any Field
The SM-8200 Digital Super Megohmmeter series are insulation resistance
meters consisting of a constant voltage power supply and a high
sensitivity current measuring element, and are designed to
measure the electrical resistance of insulation materials with
high insulating properties.

Hioki SME-8310 Plate Sample Electrode for Measuring Surface or Volume Resistance

When paired with super megohmmeters, the Hioki-SM8310 can measure the surface and volume resistance of plate samples.
Watch this video to learn how to connect the SME-8310 with the Hioki SM-8220 Super Megohmmeter.

Hioki SME-8330 Plate Sample Electrode for Measuring Surface or Volume Resistance

When paired with super megohmmeters,
the Hioki-SM8330 can measure the surface and volume resistance of liquid.
Watch this video to learn how to prepare the SME-8330 for testing,
and how to connect it with the Hioki SM-8220 Super Megohmmeter.

Measure Surface Resistance of Plate Samples with the Weight Electrode SME-8320

Pair the Hioki SME-8320 with a super megohmmeter to measure the surface resistance of plate samples.
For large insulation resistance values (greater than 10^10 ohms),
effects from surrounding noise or hums (inductance) can cause the inability to measure correctly.
For these situations, we recommend combining the Shielding Box SME-8350.
