BI's Model 3258 & Model 3239-series Contacting Conductivity Sensors are designed to accurately measure conductivity/resistivity from ultrapure water (0.056 µS/cm) to 200,000 µS/cm in clear fluids. Each sensor is available in a variety of precisely measured cell constants and materials of construction to meet many measurement needs.

BI's Model 3258 & Model 3239-series sensors are ideal for deionisation, reverse osmosis, electro-deionization, desalination, chemical purity, and other clear fluid applications.
