YOKOGAWA DC402G

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 auxilliary mA output and the pulse proportional relay outputs, thus avoiding the need for a separate controller.

The famous EXA sensor diagnostics are also present in the DC402G. Self-tuning of the excitation frequency and measuring pulses ensure optimum accuracy. The polarisation check gives on line indication of sensor fouling and early warning that maintenance is needed. A wide variety of temperature compensation possibilities (NaCl according to IEC 746-3, manual TC, preprogrammed matrices and a freely programmable 5x5 matrix), provides a high-accuracy measurement with minimum effort.
