In daily life, people seldom ask, "What is conductivity?" or hear or read about it. There are numerous publications for professionals that cover theory and research regarding this difficult subject, but few books on conductivity for the general reader have been published. To mark the launch of HORIBA’s compact ion meter LAQUAtwin, we at HORIBA have put together some fundamental knowledge on conductivity, making it as easily understandable as possible, so that ordinary readers can deepen their understanding of conductivity meters. We hope that this information will inspire you to seek further knowledge about electrochemistry, and that you will discover fresh applications of compact conductivity meters that have not occurred to us.
With the introduction of the SI unit system, “electric conductivity” has been adopted as the standard formal term, but in practice, the word “conductivity” on its own is commonly used.
