The CF60 conductivity sensor features a superior six-electrode, four-pole design. The patented arrangement of the four current electrodes around the two potential electrodes results in a reliable and precise measurement of a broad conductivity range from 1 µS/cm up to 850 mS/cm. This unique design also provides greatly reduced sensitivity to sensor fouling and polarization. Designed for ultra-sterility, the six electrodes are sealed in the FDA-compliant PEEK sensor tip without the use of o-rings or epoxies.
