Suntex EC-4110-ICON transmitter provides precise inductive conductivity measurements even in the harshest chemical conditions with chemical concentration curves, or a self-defined conversion table. Built-in product adjustment function allows fine-tuning for concentration values to minimize process contamination caused deviations. Users can even utilize MODBUS digital communication to remotely change concentration curves. The EC-4110-I is an inductive conductivity transmitter without concentration mode
