Flexibility, reliability and low maintenance are among the benefits provided by the EXA DC402G conductivity analyzer. Designed to meet the exacting requirements of measuring dual cell conductivity and resistivity in the modern industrial environment, it contains many features to ensure the best precision whatever the application. Differential, ratio, deviation, % passage or % rejection can be indicated and/or transmitted. This 4-wire converter is housed in a robust IP65 field mountable case. Two mA outputs, four relays, digital communication and a clear LCD make the DC402G a truly comprehensive package. The DC402G features PI control on the auxiliary mA output and the pulse proportional relay outputs, thus avoiding the need for a separate controller.
