Join Mike this week on Bench Boost as he explores the basics of conductivity measurements. We review the theory of how conductivity is dependent on ion concentration, charge, and mobility. He describes how contact probes work, emphasizing the cell constant and how proper probe selection to avoid poor sensitivity or signal saturation. Temperature is highlighted as a major variable, often ~2–3% per °C. Lastly we cover calibration using NIST-traceable KCl standards, and how calibrating near the sample range and controlling errors can lead to accurate and reliable data.
