Features

Toroidal Inductive Measurement Design

Adopts toroidal inductive sensing principle for non-contact measurement, resistant to strong acid and alkali corrosion, ideal for highly corrosive chemical liquid monitoring.
Custom Concentration and Conductivity Tables

Allows users to set custom conductivity-concentration lookup tables to convert and display acid/alkali concentration, compatible with various chemical solutions.
Rich Control&Communication Options

The online inductive conductivity controller is equipped with two relays, two 0/4-20mA current outputs and Modbus RS485 communication, easy integration with PLC and host systems.

Application

The AEC2-R4 inductive conductivity controller is specially developed for corrosion chemical scenarios. It is widely used for concentration monitoring of strong acid and strong alkali solutions in pickling, electroplating, chemical blending, wastewater treatment and other process. The non-contact inductive measurement avoids electrode contamination and polarization trouble, maintaining stable reading in high-concentration aggressive liquids.
