Single-parameter water treatment controller


Kontrol 40 extends our range of water-treatment control systems with accurate, repeatable and reliable single-parameter measurement of pH, ORP, conductivity, flow rate and chlorine.


Whether using Kontrol 40 as a chlorine controller in swimming pool water treatment or for legionella control, reverse osmosis or many other applications, operators receive high-resolution measurements via an intuitive programming interface, high-quality probes and real-time status bar.


Users can choose from four casing options for simplified installation, while a multilingual menu and intuitive 16-character alphanumeric display facilitate operation of the system.
