optek ACF60 conductivity sensor

Knowing the conductivity of liquid samples is a key parameter to control product quality throughout the production process.

The optek ACF60 conductivity sensor features a six-electrode, four-pole design. The arrangement of the four current electrodes around the two potential electrodes is designed to result in a more reliable and precise measurement. This design also provides greatly reduced sensitivity to sensor fouling and polarisation. The combination of an optek C800 or C8000 universal converter and the ACF60 conductivity sensor allows a wide dynamic range of 0–10 μS/cm up to 0–850 mS/cm with the same sensor (DIN EN 27888/ISO 7888 and ASTM D1125).

Applications include conductivity control for chromatography processes; pre/post column monitoring of pure, drinking and treatment water; TFF/ultrafiltration; heat exchanger control; and interface detection in food and beverage and CIP processes.
