Overview

The AC221 conductivity cell is designed for insertion in pipelines, vessels and process sample lines in power plants, ion-exchangers, reverse osmosis and chip cleaning applications. The cells are constructed with stainless steel electrodes and are resistant to polarization, requiring virtually no maintenance. A choice of cable connection methods is available, including a detachable connector that eliminates incorrect connections. Critical temperature measurement is included with a world-beating response of less than 30 seconds, enabling rapid compensation and remote output.
