Zodiac Blue Connect Gold – digital pool tester

The Zodiac Blue Connect Gold is a smart, floating digital pool tester that monitors your water quality 24/7. Its advanced 4-in-1 gold sensor measures pH, ORP (redox), salinity and temperature and sends the results directly to your smartphone, so you always know how balanced your pool or spa water is.

• 4-in-1 gold sensor for pH, ORP, salinity and temperature
• Suitable for fresh water, saltwater pools and hot tubs
• Continuous monitoring with clear alerts and dosing tips in the app

Smart 4-in-1 analysis for pools and spas

The Blue Connect Gold combines four essential measurements in one compact probe: pH, ORP, salinity and water temperature. This gives you a complete overview of your water balance without the need for separate test strips or manual test kits. The gold sensor is designed for demanding pool environments and provides stable, precise readings over a long period of time.

By tracking pH and ORP together, the device shows how effectively your disinfectant is working, while the salinity measurement helps you keep the salt level within the ideal range for your salt chlorinator. The temperature reading completes the picture, because temperature influences both comfort and chemical demand.

The tester performs several automatic measurements per day and stores the history. In the app you can view these trends over days or weeks, making it easier to detect patterns, adjust treatment and prevent water problems before they appear.

Connected control and flexible installation

The Zodiac Blue Connect Gold works together with the Fluidra Pool app, which serves as a central dashboard for your water analysis. When you are near the pool, you can read out the latest values via Bluetooth; via Wi-Fi you can also access the data remotely. The app translates the raw measurements into clear, practical advice and indicates which type of product you should add and in what quantity, based on your pool volume.

Notifications warn you when a parameter falls outside the recommended range, so you can intervene quickly and avoid cloudy water, corrosion or irritation for swimmers. For users who want additional insights, an optional premium subscription unlocks extra graphs and features on top of the standard app functions.

The Blue Connect Gold can simply float on the pool surface or, with the appropriate fitting, be mounted in the piping of the technical room. The slim design allows it to work in combination with most pool covers. The integrated lithium-ion battery is rechargeable via USB-C, so you do not need disposable batteries. Regular cleaning of the probe and periodic calibration are sufficient to maintain accurate measurements season after season.
