The Sentia Doser Secondary Unit is an extension pump designed to work alongside the Sentia Primary (base) unit. It cannot operate independently and must be connected to a Primary unit for power and control. Multiple Secondary units can be added to expand your dosing system, allowing you to manage additional supplements from a single platform. Using the Sentia app via WiFi, both Primary and Secondary dosers can be programmed and monitored directly from your smartphone. The system supports accurate and consistent dosing, helping maintain stable water parameters in marine or freshwater aquariums.
