Hioki Super Megohmmeters are high insulation resistance meters designed to measure the electrical resistance of insulation materials with high insulating properties. The SME-8330 is used for measuring the insulation resistance or volume resistance of liquid samples and consists of main and counter electrodes and a protection electrode or guard which removes leakage current through the insulator to sustain the electrodes.

Electrode for liquid samples which is electrically guarded. The total volume is 25ml. The capacitance between the main and counter electrodes is approx. 45pF. The electrode constant is approx. 500cm. The distance between both electrodes is 1mm. Outer dia. is 36mm, height is approx. 140mm. Measure resistance up to 10^19O (at 1000V) when used together with Model SM-8216.
