What is resistivity

As science and technology advance, demand has increased for simple, quick and precise classification of material properties in diverse fields such as research and development, production engineering and quality control.

According to the conventional method, resistance (Ω) was used for this purpose. However, resistance does vary depending on the type, shape and size of the material and also the measuring point. Therefore, the approved measuring method uses resistivity (Ω∙cm) which expresses absolute and real material values.

Resistivity is simply calculated by multiplying the measured resistance (Ω) with a Resistivity Correction Factor (RCF).
The resistivity measuring systems of Mitsubishi Chemical Analytech (MCCAT) have been designed to ensure easy RCF calculation and thus resistivity is measured in a simple test procedure.
