The HYDROS Digital Inline TDS Sensor is a HYDROS Sense Port accessory that allows you to conveniently monitor the performance of your reverse osmosis (RO) or reverse osmosis deionization (RO/DI) unit. This innovative digital inline TDS sensor connects to any HYDROS Sense Port and accurately monitors water quality of your RO or RO/DI unit by detecting and measuring the level of total dissolved solids (TDS) in the water. Once properly integrated to your HYDROS Control aquarium controller platform, the HYDROS Digital Inline TDS Sensor is powered by your HYDROS Control aquarium controller. By downloading the FREE HYDROS app, you can control any HYDROS-connected device with your Internet-enabled computer, smartphone, or tablet!

HYDROS is engineered, assembled and supported at CoralVue headquarters in Slidell, Louisiana USA.

Please Note: The HYDROS Digital Inline TDS Sensor requires a Hydros Control aquarium controller with an available Sense Port to operate. HYDROS Control aquarium controllers and other HYDROS accessories each sold separately.

Please Note: The HYDROS app is required to use your Internet-connected smart mobile device as a controller. The HYDROS app is downloadable via the Google Play Store and iOS App Store.

General Information
Hydros aquarium controllers are the next generation of automated aquarium devices. Rather than relying on each individual device’s brain and programming capacity, the Hydros Control units have their own CPU and control capabilities. Hydros Control devices remove the problem of incompatible ports and need to continually add modules to expand your aquarium’s automation system. This new technology is called the Hydros Sense Port. The Sense Port is an entirely new concept in aquarium monitoring technology. A Sense Port is a generic input port that can accept data from numerous different types of sensors. Drive Ports provide 12-volt power for controlling ATO pumps, cooling fans, and other devices. Hydros is the future of automation!
