KETOS is a vertically integrated water intelligence platform with intelligent hardware, bi-directional connectivity infrastructure, interactive software, and hassle-free services, all for a predictable, flat service fee.
We're transforming how water operators measure, manage, and forecast water quality and efficiency in industrial, agricultural, and municipal applications.
KETOS combines hardware, software, connectivity, automated reporting, predictive analytics, and maintenance to automate water monitoring and testing as a fully integrated platform. Our goal is to provide water operators with the visibility to identify and solve mission-critical water efficiency and water quality challenges (in real-time or before they happen). Equipped with up-to-the-minute data and predictive algorithms, operators can now ensure their water meets specific quality and safety standards.
KETOS can monitor water for 30+ parameters, including:
- Environmental factors (Total Dissolved Solids, Temperature, Conductivity, Salinity, pH, Oxidation Reduction Potential [ORP], Dissolved Oxygen)
- Inorganics (Alkalinity, Dissolved Boron, Dissolved Silica, Free Chlorine, Residual Chlorine, Total Hardness)
- Heavy metals (Chromium, Copper, Iron, Lead, Manganese, Zinc, Selenium, Mercury, Arsenic, Cadmium, Calcium)
- Nutrients (Orthophosphates, Nitrates)
