Sometimes the need differs from standardized methods, and well… If something is ought to be standardized, it doesn’t hurt for it to exist first. Below is a surface resistance bar electrode (SRB), which is an alternative approach to using the concentric ring electrode. More of the reasons may be read from this publication<\/a> in more detail. Note, it is behind a small paywall.<\/p>\n\n\n\n

The smaller handheld electrodes are designed to enable measurement of more complex test environments, e.g., directly on a conveyor belt and parts with no well-defined areas for proper placement of a bulkier electrode. In you’re not aware of what you’re looking for, get in touch via contact form<\/a> and we’ll see if we’ve got something ready, in case not, then we’ll provide you a feasibility check including estimate for cost and lead time to get something tailored.<\/p>\n\n\n\n

Standard 4-point methods<\/p>\n\n\n\n

There are two well established, methods for 4-point volume resistivity measurement of conductive plastics, here is a short comparison of them.<\/p>\n\n\n\n
