Hioki Super Megohmmeters are high insulation resistance meters designed to measure the electrical resistance of insulation materials with high insulating properties. The SME-8301 is an electrode that enables surface resistance measurement simply by pressing the electrode onto the sample and is used in conjunction with the SM-8200 series.

Surface resistance can be easily measured by simply pushing the electrode against the specimen. It measures surface resistance of anti-static related goods in a combination of mainly Model SM-8213. Measure resistance up to 10^11 Ω.
