Intuition-9 is the top-of-the-line model of water treatment controllers, integrating high-performance sensor functions, measuring instruments, liquid processing, and various data communication technologies into a single unit.
Its proven performance stands at the highest level in the water treatment industry. It achieves intuitive operability through an easy-to-setup large touch panel display and swipe functionality.
Management systems can be configured for multiple cooling towers, boilers, closed-loop systems, and all water treatment-related processes.
It monitors and manages based on inputs from various water quality sensors and measurements from field devices that measure corrosion rate, level, temperature, pressure, and more. Operating 24/7, 365 days a year, it notifies both on-site personnel and remote staff about system performance status.
Furthermore, using Intuition-9 enables comprehensive management with high reliability, not limited to water treatment alone.
Centralized management of independent equipment and remote data logging, etc.
