Measure the Resistivity of Electrically Guarded Liquid Samples

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. Total volume is 25 ml. Capacitance between main and counter electrode is approx. 45 pF. Electrode constant is approx. 500 cm. Distance between both electrodes is 1 mm. Outer dia. is 36 mm, height is approx. 140 mm. Measure resistance up to 10^19Ω (at 1000 V) when used together with Model SM-8216.

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.

SME 8330 Liquid Sample Electrode: How to Disassemble and Clean

The Hioki-8330 is made up of a main electrode, counter electrode terminal, insulator to remove leakage current from these parts, and protective electrodes. In addition, the insulator is made of chemically stable materials (such as teflon, Kel-F and tiflon), while nickel plating is used for the electrode surface to bring uniformity to the electrolytes and chemically strengthen them. The electrode is intelligently designed so that it can be conveniently disassembled for cleaning and easily reassembled, enabling users to test and wide range of samples.
