CRIUS®4.0 is a powerful, multi-channel instrument controller designed for high-performance water and process monitoring across industrial, municipal, and commercial applications. With remote access, Industry 4.0 compliance, and compatibility with a wide range of sensors, it delivers precise control, real-time data visibility, and significant efficiency gains. Part of a broader controller range, CRIUS®4.0 offers greater functionality than its CRONOS® counterpart, supporting up to four sensors with analogue outputs, relays, and expandable options via linked units. The controller features a colour display, optional 3G/4G or LAN connectivity, and built-in data logging as standard. Remote access via the MQTT protocol enables secure, live, encrypted data to be accessed across platforms—enhancing responsiveness and decision-making. Advanced features like multiple PID loops, variable speed drive (VSD) control, and self-cleaning sensor compatibility make it ideal for energy optimisation and reduced downtime. Applications include: Drinking water and wastewater treatment Swimming pool and spa management (with improved bathing water quality and reduced energy costs) Industrial processes in food and beverage, pulp and paper, and vegetable washing Municipal systems requiring high-accuracy chlorine, dissolved oxygen, or coagulation control Available in multiple languages and built to handle demanding environments, CRIUS®4.0 is the preferred choice for customers needing advanced control, scalability, and reliability in one smart package. For simpler applications, the CRONOS® controller is also available.
