Stop Guessing When Your Pool Water Is Out of Balance
Check pool water across seven parameters — smartphone app readings and range alerts, without separate tests for temperature, pH, ORP, EC, TDS, salt, and specific gravity.
Why Is This Pool Water Tester Perfect for You?
✔ Seven water measurements in one device: Measure temperature, pH, ORP, EC, TDS, salt, and specific gravity with one compact digital tester. These readings help assess water balance, sanitizing performance, conductivity, dissolved solids, and salinity.
✔ Read results in a smartphone app: View measured results in the accompanying app, available on the App Store and Google Play. Clear readings and alerts when values move outside the desired range make it easier to respond to changing pool conditions.
✔ Monitor water balance and sanitizing performance: Use pH readings to check whether disinfectants can work efficiently, and ORP readings to assess the water’s oxidizing ability and sanitizing performance. Temperature readings can also help identify conditions that may reduce chlorine effectiveness or encourage microorganisms.
